How to fix elif expected expression error in python-CodePudding

import win32api,time
while True:
    a = win32api.GetKeyState(0x57)
    if a <0:
     print("w")
    a = win32api.GetKeyState(0x53)
    elif a <0:
    print('s')
    time.sleep(0.1)

im super new to python the line elif a<0 gives me the error ```expected expression`` what do i do to make it work? thanks

CodePudding user response：

You need a correct indentation in your code when you use if and while structures, because that will determine the instructions that execute in a certain moment:

import win32api, time

while True:
    a = win32api.GetKeyState(0x57)
    if a < 0:
        print("w")
    a = win32api.GetKeyState(0x53)
    if a < 0:
        print('s')
    time.sleep(0.1)
