There are times when you need the entire block of code as a string and want this code to execute as part of a bigger python program. IN this article we will see how we can pass code as a string to a variable and then use that variable in a wrapper program which will then execute this program as a python code.
The exec() function is used to execute the code. The code has to be embedded within three “.
Example
code = """
numbers = [11,33,55,39,55,75,37,21,23,41,13]
for num in numbers:
if num%2 == 0:
print ('the list contains an even number')
break
else:
print ('the list doesnot contain even number')
"""
exec(code)Output
Running the above code gives us the following result −
the list does not contain even number.
