pycharm各种警告问题

shadows name from outer scope

这种警告是函数内部的名称与外部名称重复了，看下面例子

def cleanword(word):
    # Return word in lower case stripped of whitespace
    return word.strip().lower()


for word in datafile:
    word = cleanword(word)
    if len(word) <= 6:
        continue
    print(word)

在for循环里word与函数cleanword里重复了，解决办法就是将for循环中word修改一下

def cleanword(word):
    # Return word in lower case stripped of whitespace
    return word.strip().lower()


for words in datafile:
    words = cleanword(words)
    if len(words) <= 6:
        continue
    print(words)
