如何从文件中的每一行获取第二个和第四个字

Question

示例：文件将被称为“Sentences.dat”。它将有这些线路

Name #3 is Bob

Name #7 is Marie

Name #8 is Kate

Name #2 is George

我想将它们保存到一个dictionary，其中它们的编号是key，名称是value。这就是我目前所拥有的

file = open("Sentences.dat","r")
dictNames = {}
line = 1
while True:
    content = file.readlines()[line]
    split = content.split()
    dictNames[split[1]] = split[3]
    line = line + 1

Answer 1

这是另一种有效的方法

dictNames = {}
with open('Sentences.dat', 'r') as f:
    for line in f:
        words = line.split()
        dictNames[words[1]] = words[3]
