如何在文本文件中剪切线条？

Question

我有一个这种格式的文本文件：

Item1       20  0   
Item2       10  1
Item3       5   0
Item4       15  1
Item5       25  1
Item6       30  0

我如何.readlines()只能附加＆＃34; Item1＆＃34;和＆＃34; Item2＆＃34;等。到列表，并留下数字和空格？

Answer 1

您可以尝试下面的内容，

l = []
with open('/path/to/the/file') as file:
    for line in file:
        l.append(line.split()[0])
print(l)

通过list_comprehension。

print([line.split()[0] for line in open('/path/file')])

Answer 2

lines = []
with open("text.txt", 'r') as fin:
    lines = fin.readlines()

for line in lines:
    print line.split(" ")[0]

Answer 3

  

使用列表理解：

with open('sometext.txt', 'r') as f:
    list1 = f.readlines()
    print([ part.split(" ")[0] for part in list1 ])
