I want to check if the input is str or is int & if it's str repeat the loop

[HLD202]

I want to check if The input is 'str' or it's 'int' and if it's 'str' repeat the loop...
but i don't know how to check if the input was for example: dds

while True:
    rows_input = input("Enter Rows: " )
    cols_input = input("Enter Cols: " )
    
    if int(rows_input) and int(cols_input): #here i'm trying to check it but i get error
        # i want to check if it's possible to convert the str to int then close the loop but i can't
        break
    else:
        print("you have to Enter a Number not string... [Try again]")

# Here are inputs
>>> Enter Rows: dds
>>> Enter Cols: 2

Error:
Traceback (most recent call last):
  File "Matrix_Calculator.py", line 5, in <module>
    if int(rows_input) and int(cols_input): #here i'm trying to check it but i get error
ValueError: invalid literal for int() with base 10: 'dds'

but if the inputs be int, there's no problem and no error and the loop ends

>>> Enter Rows: 2
>>> Enter Cols: 2

Error:
No Error
