To check python program execution; In this tutorial, you will learn how to find or check execution time of a simple program or script in python.

The execution time of a program is defined as the time spent by the system to execute a task.

### Algorithm to check the execution time of a Sample Python Program/Script:

- First of all, import the datetime module in your python script/program.
- Take values from the user.
- Find the initial time by using now() function and then assign it to a variable which is time_start.
- Complete the task in the program.
- Here, we will also find the current time and assign it to a variable which is time_end.
- To know the execution time simply find the difference between the time_end and time_start i.e time_end – time_start.

### Python program to determine the execution time of python script/program

See the following python program to check the execution time of the program or script.

```
#Python Program to find the execution time of python script
# importing the modules
from datetime import datetime
A=int(input("Enter the A value: "))
B=int(input("Enter the B value: "))
time_start=datetime.now()
C = A + B
print("A + B = :",C)
time_end=datetime.now()
e= time_end - time_start
print("The execution time of python program is : ",e)
```

**Output**

Enter the A value: 8 Enter the B value: 5 A + B = : 13 The execution time of python program is : 0:00:00.000054
