Python Exercise: Execute a string containing Python code

Last update on December 27 2024 13:22:33 (UTC/GMT +8 hours)

Write a Python program to execute a string containing Python code.

Sample Solution:

Python Code:

# Define a string variable 'mycode' containing a Python code as a string
mycode = 'print("hello world")'

# Define a multi-line string variable 'code' containing Python code as a string
code = """
def mutiply(x,y):
    return x*y

print('Multiply of 2 and 3 is: ',mutiply(2,3))
"""

# Execute the Python code represented by the string stored in the variable 'mycode'
exec(mycode)

# Execute the Python code represented by the multi-line string stored in the variable 'code'
exec(code) 

Sample Output:

hello world                                                                                                   
Multiply of 2 and 3 is:  6  

Explanation:

In the exercise above the code utilizes the "exec()" function to execute Python code represented as strings ('mycode' and 'code'). It executes the Python code inside these strings, printing "hello world" using 'exec(mycode)' and defining a function "mutiply()" and performing a multiplication operation using 'exec(code)'.
