Answer 2

使用open file和split（）：

with open('text.txt') as f:
    strings = f.readlines()
    data = [string.split() for string in strings]

Answer 3

您可以将string.split应用于文件中的每一行：

import string

with open('text.txt') as text:
    result = map(string.split, text)

使用Python 3，您需要实现map，否则文件在关闭之前无法读取：

    result = list(map(string.split, text))

但是，string.split已弃用，仅适用于str个对象，而不适用于unicode。更通用的解决方案是创建列表解析：

    result = [line.split() for line in text]

Answer 4

with open('text.txt') as file:
    lines = file.readlines()        # Creates a list of lines
    for line in lines:
        line = line.split()         # Split each line into list of "words"

这为您提供了一个可能合理的嵌套列表。如果你拼命想要3个列表，请使用：

evalvar = ""
count = 0
for line in lines:
    count += 1
    evalvar += "list"+str(count)+" = "+str(line)+";"
exec(evalvar)                                         # Runs the evalvar which has
                                                      # code in it.
