Question

我正在尝试将列表中的每个单词打印到单独的行中，但是它会将每个字母打印到单独的行上

Words = sentence.strip()
for word in sentence:
    print (word)

我的完整代码（对任何想知道的人）是：

import csv
file = open("Task2.csv", "w")
sentence = input("Please enter a sentence: ")
Words = sentence.strip()
for word in sentence:
    print (word)
for s in Words:
    Positions = Words.index(s)+1
    file.write(str(Words) + (str(Positions) + "\n"))
file.close()

Answer 1

你忘了分句并在第一个循环中使用“单词”而不是“句子”。

#file = open("Task2.csv", "w")
sentence = input("Please enter a sentence: ")
Words = sentence.split()
for word in Words:
    print (word)
for s in Words:
    Positions = Words.index(s)+1
    #file.write(str(Words) + (str(Positions) + "\n"))
#file.close()

<强>输出：

C:\Users\dinesh_pundkar\Desktop>python c.py
Please enter a sentence: I am Dinesh
I
am
Dinesh

C:\Users\dinesh_pundkar\Desktop>

Answer 2

您需要使用str.split()代替str.strip()。

str.strip()仅删除字符串中的前导和尾随空格：

>>> my_string = '  This is a sentence.   '
>>> my_string.strip()
'This is a sentence.'

str.split()执行您想要的操作，返回字符串中单词的列表;默认情况下，使用空格作为分隔符字符串：

>>> my_string = '  This is a sentence.   '
>>> my_string.split()
['This', 'is', 'a', 'sentence.']

因此，您的代码应该更像：

words = sentence.split()
for word in sentence:
    print(word)

如何打印列表中的单个单词？
