unsupported operand type(s) for / 'str' and 'int' in python code example

Example 1: python unsupported operand type(s) for /: 'str' and 'str'

# Error:
TypeError: unsupported operand type(s) for /: 'str' and 'str'
    
# Solution:
# You're probably mixing strings and integers. Make sure to either 
# convert integers to strings with str(int) or strings to integers/floats
# with int(string) or float(string) depending on what you're doing.

Example 2: TypeError: unsupported operand type(s) for +: 'int' and 'str'

do not combine int with string !
Example:int + string = error
correct example: int + int = no error 
                 string + string = no error
