Python 2.7 逐行读取文件时删除换行符

我编写了一个代码，它接收一个文件并逐行读取，但当它打印时，在每行之间添加了一个换行符。这是我的密码：

in_file = open("in.txt", "r")
line_number = 0
for line in in_file:
    print "Line "+ str(line_number) + " " + "("+ str(len(line)) + " " + "chars): "+ str(line)
    line_number += 1

它打印这个：

Line 0 (13 chars): I am a file.

Line 1 (16 chars): This is a line.

Line 2 (22 chars): This is the last line.

我怎样才能摆脱休息呢？谢谢

使用

从行尾替换换行符。替换（'\n'，''）

---

从行中删除新行字符，或在打印语句中不打印新行。在本例中，我没有打印新行：

in_file = open("in.txt", "r")
for num, line in enumerate(in_file, 1):
    print "Line", num, "(", len(line), "chars):", line,

可能重复的

in_file = open("in.txt", "r")
for num, line in enumerate(in_file, 1):
    print "Line", num, "(", len(line), "chars):", line,
