我正在尝试创建一个脚本，该脚本将查看文本文件并将每个单词作为单独的元素存储在列表中。
当尝试使用.split（）时，似乎没有将字符串拆分为单个元素。

答案 0 :(得分：1)
尝试：
all_words = word.split()
print(all_words)
split返回一个list，它不会更改原始的string。
更新（以使所有单词集中在一个列表中）：
RanTxtString = open("randomText.txt", "r")
all_words=[]
for word in RanTxtString:
all_words = all_words+word.split()
print(all_words)
