Python - readlines

Question

有没有一种方法可以让python读取行，只使用前10个字符，然后将它们赋给一个变量？

Remove_example= 'example'
Remove_at= '@'
#Remove_Agent='

filepath = 'Older WinCollect Agents on Version 728.txt'
with open(filepath) as fp:
   line = fp.readline()
   print(line[0][10])
   cnt = 1
   while line:
       print("Line {}: {}".format(cnt, line.strip(),).replace(str(Remove_example),'').replace(str(Remove_at),''))
       line = fp.readline()
       cnt += 1

我不想把静态删除行变量

def get_line_fronts(filepath: str) -> list:
    """Get list of first 10 characters in each line in a file."""
    line_fronts = []
    with open(filepath, "r") as fh:
        for line in fh:
            line_fronts.append(line[:10])
    return line_fronts


filepath = 'Older WinCollect Agents on Version 728.txt'
for line_front in get_line_fronts(filepath):
    # do whatever
