Question

这是我目前的代码：

with open('Finna.txt') as bigtxt:
        for l in bigtxt:

            l = l.capitalize()
            print l

我尝试在上面列出的文本文件“Finna.txt”上调用上面使用的capitalize（）方法

Are there upcoming networking sessions?
Are there walk in hours during the summer?
are there walk in hours today?
Are there walk-in hours during finals?
are there work opportunities for freshmen in engineering career

期望每一行都是大写的，如果它还没有，但唯一返回的是

are there work opportunities for freshmen in engineering career

这是没有资本化的。我在这做错了什么？抱歉，如果这是一个非常基本的问题，我只是开始使用Python。在发布之前，我尝试用我的问题搜索类似的问题。

Answer 1

使用您提供的代码和文本，输出似乎很好。

但是，我猜你的'Finna.txt'中可能存在一些空格或隐形字符。你可以试试这样的东西 -

with open('finna.txt') as bigtxt:
        for l in bigtxt:

            l = l.strip().capitalize()
            print l

Answer 2

你可以试试这个：

f = open('Finna.txt')read().splitlines()

new_f = [i[0].upper()+i[1:] for i in f]

输出是现在大写的所有行的列表：

['Are there upcoming networking sessions?', 'Are there walk in hours during the summer?', 'Are there walk in hours today?', 'Are there walk-in hours during finals?', 'Are there work opportunities for freshmen in engineering career']

Answer 3

您可以使用list-comprehension和lstrip()/rstrip()每行，然后capitalize()和join()进行打印：

with open('test.txt.', 'r') as f:
    print '\n'.join([x.lstrip().rstrip().capitalize() for x in f])

输出：

Are there upcoming networking sessions?
Are there walk in hours during the summer?
Are there walk in hours today?
Are there walk-in hours during finals?
Are there work opportunities for freshmen in engineering career

Answer 4

简单代码只需用大写字母替换

file = open('Finna.txt).read().splitlines()
for word in file:
    st = word.replace(word, word.capitalize())
    print(st)

输出将是：

Are there upcoming networking sessions?
Are there walk in hours during the summer?
Are there walk in hours today?
Are there walk-in hours during finals?
Are there work opportunities for freshmen in engineering career

如何大写文本文件中每行第一个单词的第一个字母？
