# Check if the input is numeric
if input_str.isdigit():
num = int(input_str)

try:
num = int(input_str)
except ValueError:
print(f”Error: ‘{input_str}’ is not a valid integer.”)
import re
input_str = “$1,200”
cleaned_str = re.sub(r'[^\d]’, ”, input_str) # Remove any non-digit characters
try:
num = int(cleaned_str)
print(num)
except ValueError:
print(“Invalid integer.”)
