Why is my code not working, please help.

Question

I entered this code into Sololearn's code playground and it worked but it didn't in python shell. this was the code:

n1 = input("Enter the first number: ")
print(n1)
op = input("Enter the opperation: ")
print(op)
n2 = input("Enter the second number: ")
print(n2)

if op == str("+"):
print(int(n1) + int(n2))

elif op == str("-"):
print(int(n1) - int(n2))

elif op == str("*"):
print(int(n1) * int(n2))

elif op == str("/"):
print(int(n1) / int(n2))

else:
print("only enter the common 4 types of opperatiors")

Answer 1

By Python shell I think you mean the interactive mode (with the >>> prompt).

The empty lines between your "if" statements and the subsequent "elif" cause the interactive interpreter to close the "if" context (making "elif" a surprise syntax error).
Remove the empty lines.

This is not a problem for scripts, just interactive mode.

Answer 2

are you sure its "elif"? why don't you try it with " switch" command instead?

Answer 3

I haven't learned that yet
