来自文本文件的小写

Question

我有一个文件,我试图以小写字母转换单词.这就是我到目前为止所拥有的

with open('example.txt', 'r') as fileinput:
   for line in fileinput:
       lines = fileinput.lower()

AttributeError: 'file' object has no attribute 'lower'

Answer 1

您正在小写文件对象,而不是行.

with open('example.txt', 'r') as fileinput:
   for line in fileinput:
       line = line.lower()

会更好..

Answer 2

代替

lines = fileinput.lower()

把这个:

line = line.lower()

完整代码:

with open('example.txt', 'r') as fileinput:
    for line in fileinput:
        line = line.lower()

这可以正常工作.
