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

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 $(\text{'}$number $1\text{'}$ operator 'number $2\text{'})$: $")$

# Step $2$: Parse Input

def parse$\_$input$($expr$)$:

try:

except ValueError:

return None, None, None

# Step $3$: Validate Input

# Step $4$: Perform Calculation

def calculate$($opr$1,$ oprtr, opr$2)$:

elif oprtr $==\text{'}-\text{'}$:

elif oprtr $==\text{'}/\text{'}$:

return float$(\text{'}$inf$\text{'})$ # Return infinity for division by zero

return opr$1/$ opr$2$

# Step $5$: Handle Errors

def handle$($result$)$:

if result is None:

# Step $6$: Print Result
