The following code returns into a nice readable output.
以下代码返回一个很好的可读输出。
def add_line_remove_special(ta_from,endstatus,*args,**kwargs):
try:
ta_to = ta_from.copyta(status=endstatus)
infile = botslib.opendata(ta_from.filename,'r')
tofile = botslib.opendata(str(ta_to.idta),'wb')
start = infile.readline()
import textwrap
lines= "\r\n".join(textwrap.wrap(start, 640))
tofile.write(lines)
infile.close()
tofile.close()
This is the output, now I would like to remove all the characters until and including the _
这是输出,现在我想删除所有字符,直到并包括_

To get all text on a line after a underscore character, split on the first _
character and take the last element of the result:
要在下划线字符后的行上获取所有文本,请在第一个_字符上拆分并获取结果的最后一个元素:
line.split('_', 1)[-1]
This will also work for lines that do not have an underscore character on the line.
这也适用于行上没有下划线字符的行。
Demo:
>>> 'Grp25_QTY47 5'.split('_', 1)[-1]
'QTY47 5'
>>> 'No underscore'.split('_', 1)[-1]
'No underscore'
Translating this to your code:
将其翻译成您的代码:
import textwrap
ta_to = ta_from.copyta(status=endstatus)
with botslib.opendata(ta_from.filename,'r') as infile:
with botslib.opendata(str(ta_to.idta),'wb') as tofile:
for line in textwrap.wrap(next(infile), 640):
line = line.split('_', 1)[-1]
tofile.write(line + '\r\n')
