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')
