The time.struct_time values object can be represented using both attributes and indices. The function time.asctime helps in the conversion of time. struct_time into a format that is readable in human string form.
How to use Python time epoch?
An epoch in Python is defined as a time instance selected as the start of a specific era. To get information on a Python epoch, you need to pass zero as an argument to the time. gmtime function. The epoch is represented as the time 00:00:00 UTC as of 1970, 1st January, and it is also represented as 1970-01-01T00:00:00ZISO8601. Following Python code showcases the application of Python time epoch as shown below: – Python Code: Output:
How to use Python time.time() for Timer?
The time function in the Python time module returns a number of seconds that have passed since the last defined epoch. It returns seconds in the form of floating-point data type. The syntax for the Python time.time() function is represented as shown below: – Syntax: The following code displays how to use the time function in Python: – Python code: Output: The above example shows the floating-point value and number of seconds. The time function can be utilized to compute the elapsed wall-clock time by taking two reference points. The program for elapsed wall clock time is as shown below: Python Code: Output:
How to use Python time.ctime()?
The ctime function in the Python time module takes an argument as the seconds, which is passed as an epoch and as an output, it provides a local time in string data type. The seconds elapsed since the last epoch becomes input for ctime function. The time function can also be used as an input or argument in the ctime function. The purpose of the function is to deliver output in an understandable format or in format that a human can understand. The syntax for ctime() function of Python time module is shown below: Syntax: The following Python code helps in illustrating the example of ctime() function in the Python module. Python code: Output: The above code begins with importing the time module. The variable start_time_guru99 is initialized with the time method, and similarly, the variable end_time_guru99 is initialized. The variables are then converted to ctime format, which converts the time format to string format. This Python code computes the difference of the two initialized variables to arrive at the time elapsed value. The above output displays a human-readable string value. It also provides the difference in floating-point format.
How to use Python time.sleep() for Timer?
The sleep function available in the Python time module helps in slowing down the execution of a program. It halts the program execution for a few seconds that is passed as an argument into the sleep function. It also accepts a floating-point number as an input to have a more accurate sleep time or have a halt in the present execution thread. The syntax for sleep function in Python time module is represented as shown below: – Syntax: The application of sleep function extends to several programming situations. One situation could be database commit, and another situation could be to wait for the file to finish. The following code displays the sleep function of time module as shown below: – Python code: Output:
How to use Python time. Python time.gmtime()?
The gmtime() function in time module of Python takes an argument in terms of a number of seconds that is passed post the completion of epoch. The function returns output in the form of struct_time or UTC format. Here, UTC means universal time coordinated. The syntax of gmtime() function is as follows: – Syntax The following code is an example on how to use gmtime() function of Python as shown below: – Python code: Output: In the above code, the time function of the time module of Python is passed as an argument into the gmtime function of, which provides the end-user with the structured time format as an output.
How to use time.clock() function in Python?
The clock function in the time module of Python returns processing time as an output to the end-user. The main role of the function is to facilitate benchmarking and performance testing. The function provides the accurate or correct time taken by the Python code segment to complete its execution. The output provided by the function is the more accurate result than the other time-related functions. The syntax for clock function is represented as shown below: – Syntax: Since the clock function is deprecated from Python version 3, the programmer can use time.perf_counter() function and time.process_time() function to assess the performance of the code developed by them.
How to use Function time.Thread_time in Python?
The thread_time function of the time module of Python gives the sum of system time and the CPU time for an active running thread. The function returns a floating-point value, and it does not include the time the code spends or takes when the sleep function is invoked. The function is utilized for specific threads only, and it can be used to record the time difference between two reference points. The following example shows the application of the thread time function. Python code: Output: The above code returns the time difference between the start and ends time spent in the thread named as thread example, and it returned the difference as 1.029 respectively.
How to use function time.Process_time() in Python?
The process time function in the time module of the Python returns the reference of time in terms of fractional seconds and floating-point value. The function gives the sum of system time and the current progress of CPU time. This function displays a similar attribute as present in the thread_time function of not including the time spent in time.sleep function(). It also creates a reference that is based on a specific process. Due to this attribute, the time difference between two consecutive references is undertaken. The following code helps in describing the usage of the process time function as shown below: – Python code: Output: The above code records the time between the start and the end time. Between the start and end time difference, the execution of the process code gets recorded as a process and becomes part of elapsed time.
How to use function time.Perf_counter() in Python?
The Perf_counter function provides a high-precision or accurate time value. The perf_counter function delivers an accurate or precise time between two established reference points that is a start and end time. The following code helps in describing the performance counter as shown below: – Python code: Output: In the above code, a simple loop is applied to validate the time taken by the function performance counter to record time between the start and the end time. As the output showcase, the timer delivers a high precision output.
How to check the time zone in Python?
In Python, there are two properties under the time function of the time module that provides the end-user with information pertaining to the time zone.
The first one is the time.timezone property, and the second one is time.tzname. The time.timezone returns the offset of non-DST or the local time zone under UTC format. The time.tzname returns a tuple that comprises DST and non-DST or local time zones.
The syntax for time.timezone is shown as follows: – Syntax: The syntax for time.tzname is shown as follows: – Syntax: The following code would showcase how to use time zone properties in Python: – Python code: Output:
How to develop a basic Python timer?
Python timer is defined as a library or class that helps in the management of the time complexity of the code. A timer enables to create a system in the existing code snippet and check how much time an existing code takes to finish the task. Python timers such as performance counter, process timer, and using time function as described above can be used to assess the performance of existing codes in terms of execution standpoint.
Summary
Other Important Python Timer Modules: Python provides several modules that help in time management as well as it helps in the analysis of code. The other modules that could be used in time and effort analysis for codes that are written in Python are as follows:
Term down: This is a Python timer of advanced nature, and it utilizes different ASCII characters. They are used to produce simple countdown timers. MobTimer: Python: This is another GUI-based timer in Python that, when launched, provides the end-user full-screen timers with multiple options. Ctimer: This is a timer module in Python that provides precision up to nanoseconds. It utilizes the C language APIs to record the time accurately.
