python - 我的文件中有错误，但在控制台中它可以工作

Question

当我在 run.py 中编写它时，它有意外的缩进，但是当我在 python 控制台中编写它时，它的工作原理

from pip._vendor.distlib.compat import raw_input


def hello(a, b):
    if b != 0:
        wynik = a/b
        return wynik
    else:
        wynik = "No result"
        return wynik



a = raw_input('Number A:')
b = raw_input("Number B:")

    if not a is None and not b is None:
    print(hello(float(a),float(b)))
    else:
    print("A or B must be filled")

raw_input()

这是日志：

C:\Users\Student\PycharmProjects\untitled>run.py
  File "C:\Users\Student\PycharmProjects\untitled\run.py", line 17
    if not a is None and not b is None:
    ^
IndentationError: unexpected indent

缩进无效，替换这个：

    if not a is None and not b is None:
    print(hello(float(a),float(b)))
    else:
    print("A or B must be filled")

有了这个：

if not a is None and not b is None:
    print(hello(float(a),float(b)))
else:
    print("A or B must be filled")
