Python：从单词列表中创建一个句子（逗号和句点前不应有空格）

Question

想要的输出：如果没有人爱他，他可能会努力去爱自己

words = ["if", "nobody", "loved", "him", ",", "he", "probably", "struggled", "to", "love", "himself", "."]

for i in range(len(words)):
    if words[i] == "." or ",":
        continue
    sentence = " ".join(words)

print(sentence.capitalize())

但是，它不起作用。如何在列表中找到逗号和句点

Answer 1

首先，words[i] == "." or ","总是正确的。所以你总是进入continue，这就是你不能打印任何东西的原因。您应该将其更改为word == "." or word == ","

其次，您可以在循环中迭代单词

正确代码：

words = ["if", "nobody", "loved", "him", ",", "he", "probably", "struggled", "to", "love", "himself", "."]

sentence = ""
for word in words:
    if word == "." or word == ",":
        sentence += word
    else:
        sentence += " "
        sentence += word
print(sentence.strip().capitalize())
