how to fix this python code Please enter the mathematical expression ( ' number 1 ' operator 'number 2 ' ) : 2 / 0

how to fix this python code Please enter the mathematical expression ('number 1' operator 'number 2'): 2/0
Invalid input. Divison by 0 is not permissible.
this is code use
# Step 1: Accept Input
def get_input():
expr = input("Please enter the mathematical expression ('number 1' operator 'number 2'): ")
return expr
# Step 2: Parse Input
def parse_input(expr):
try:
opr1, oprtr, opr2= expr.split()
return float(opr1), oprtr, float(opr2)
except ValueError:
return None, None, None
# Step 3: Validate Input
def validate(opr1, oprtr, opr2):
valid_operators =['+','-','*','/']
if oprtr not in valid_operators:
return False
return True
# Step 4: Perform Calculation
def calculate(opr1, oprtr, opr2):
if oprtr =='+':
return opr1+ opr2
elif oprtr =='-':
return opr1- opr2
elif oprtr =='*':
return opr1* opr2
elif oprtr =='/':
if opr2==0:
return float('inf') # Return infinity for division by zero
return opr1/ opr2
# Step 5: Handle Errors
def handle(result):
if result is None:
print("Error: Division by zero")
return True
return False
# Step 6: Print Result
def print_result(result):
print("Result:", result)
# Step 7: Repeat or Quit
def ask_repeat():
response = input("Do you want to perform another operation? (y/n): ").lower()
return response.startswith('y')
# Main Function
def main():
while True:
expr = get_input()
opr1, oprtr, opr2= parse_input(expr)
if not opr1 or not oprtr or not opr2:
print("Invalid input. Division by 0 is not permissible.")
continue
if not validate(opr1, oprtr, opr2):
print("Invalid operator. Please enter a valid operator (+,-,*,/).")
continue
result = calculate(opr1, oprtr, opr2)
if handle(result):
continue
print_result(result)
if not ask_repeat():
break
if __name__=="__main__":
main()
