readlines给了我额外的换行符python2.6.5 [英] readlines gives me additional linebreaks python2.6.5

问题描述

我对以下代码有疑问:

file = open("file.txt", "r")
lines = file.readlines()
print lines[0]
print lines[1]
print lines[2]
file.close()

此代码使我在两行之间换行.所以输出是这样的:

This code gives me linebreaks between the lines. So the output is something like this:

line0

line1

line2

如何解决?

推荐答案

print 添加换行符.从该行中删除换行符:

print adds a newline. Strip the newline from the line:

print lines[0].rstrip('\n')
print lines[1].rstrip('\n')
print lines[2].rstrip('\n')

如果您仍将整个文件读入列表 ，则可以选择使用

If you are reading the whole file into a list anyway, an alternative would be to use str.splitlines():

lines = file.read().splitlines()

默认情况下会同时从行中删除换行符.

which by default removes the newlines from the lines at the same time.
