Python 3 – time time() Method
The time() method is a built-in method of Python’s time module that returns the current time in seconds since the Epoch. This method can be used to measure the execution time for a piece of code, or to get the current time for other purposes. In this article, we will discuss the syntax of the time() method, its parameters, and how to use it in a Python program.
Syntax
The syntax for the time() method is as follows:
time.time()
This method takes no parameters and returns the current time in seconds since the Epoch (January 1st, 1970 at 00:00:00 UTC).
Example
Let’s take a look at an example that demonstrates the use of the time() method:
import time
start_time = time.time()
# Code to be measured for execution time goes here
end_time = time.time()
elapsed_time = end_time - start_time
print("Elapsed time: ", elapsed_time, " seconds")
In this example, we import the time module and call the time() method twice – once to get the start time and again to get the end time after executing some code. We then calculate the elapsed time by subtracting the start time from the end time and print the result.
Output
The output of this program should look something like the following:
Elapsed time: 0.0002942085266113281 seconds
Conclusion
In conclusion, the time() method is a useful tool for measuring the execution time of your Python programs. By using this method, you can quickly determine which sections of your code are slow and which are fast. Additionally, you can use the current time returned by the time() method for other purposes, such as timestamping data. Overall, understanding the time() method is an important part of becoming a proficient Python programmer.
