python - 用 python 将文件分割成带有计数器的新行

Question

我想将包含制表符分隔的单词列表的文件拆分为一个“列表”，单词前面带有数字。

因此，如果输入文件包含此内容(其中单词之间的空格是制表符):树车屋毯

我想要这样的输出:

1 tree
2  car
3  house
4 blanket

我已经让这段代码可以打印出“单词列表”，但不确定如何在单词前面获取计数器:

#!/usr/bin/env python

import csv

with open ("commonwords.tsv") as file:
  for line in file:
    print line.replace("\t","\n") 

谢谢

您可以使用enumerate :

import csv
with open("commonwords.tsv") as f:
    for line in f:
        line = line.replace("\t", "\n")
        for ind, word in enumerate(line.split(), 1):
            print "{0} {1}".format(ind, word)
1 tree
2 car
3 house
4 blanket

不确定您是否希望计数重置每行或继续到末尾:

with open("commonwords.tsv") as f:
    line = f.read().replace("\t", "\n")
    for ind, word in enumerate(line.split(), 1):
        print "{0} {1}".format(ind, word)

您也可以只拆分而不替换:

with open("commonwords.tsv") as f:
    lines = f.read().split()
    for ind, word in enumerate(lines, 1):
        print "{0} {1}".format(ind, word)
