Python program to execute Python code from the string

Python program to execute python code from a string

We have a block of code stored in a string and we will write a python program to execute this string's code.

Example:

Input string:

codeStr = """ 
print("Hello! Running python code from string")
a = 43
b = 3
print(a%b)	
"""

Output:
Hello! Running python code from string
1

Python provides a function for executing the code that is stored inside a variable. The exec() function does the job in Python.

Syntax:

exec(code_string)

It takes in the string which contains the code.
