为什么我的字符串中出现不需要的换行符? [英] Why am I getting unwanted newline in my string?

问题描述

这应该很简单，这很愚蠢.但是我无法使它正常工作.我有一个在读取文件时定义的标题:

This should be so simple, it's silly. But I can't get it to work. I have a header which I define while reading a file:

    if "[gene=env]" in line or "[gene=HIV2gp7]" in line:
        header = line

现在此标头看起来像> lcl | NC_001802.1_prot_NP_057856.1_8 [gene = env]" ，我需要在其上附加一个数字，如下所示:> lcl | NC_001802.1_prot_NP_057856.1_8 [gene = env] 1"

now this header looks something like ">lcl|NC_001802.1_prot_NP_057856.1_8 [gene=env]" I need to attach a number to it like so: ">lcl|NC_001802.1_prot_NP_057856.1_8 [gene=env]1"

我有100个相同的标题，必须将其编号为1到100但是，无论我如何尝试，我都无法在同一行上找到该号码.输出始终为

I have 100 identical headers, which have to be numbered 1 through 100 But whatever I try, I can't get the number on the same line. The output is always

>lcl|NC_001802.1_prot_NP_057856.1_8 [gene=env]
1
>lcl|NC_001802.1_prot_NP_057856.1_8 [gene=env]
2

等

我尝试过:

number = 0
    for item in randoms[group_name]:
        number+=1
        headerx = str(header)+str(number)
        print(headerx)

以及其他无数的东西，但是无法正常工作.

and countless other things, but can't get it to work.

推荐答案

我假设您正在使用 readline 或 readlines 从文件中获取行-如果因此，每一行将以 \ n (换行符)结尾.您需要删除这些内容:

I'm assuming you're getting your lines from a file using readline or readlines - if so, each line will end with a \n (newline) character. You need to strip those off:

line = line.rstrip('\n')
