最佳答案
只需过滤行，然后使用join。
import re
with open('log_file') as file:
union = ''.join(filter(lambda line: re.match(r'\w+'), file.readlines()))
# change the regex as per your definition of 'special characters'.
关于 python 3 : Join lines of file if its not endswith a special character，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/48397272/
