Python 删除文件每一行的行号思路解读

这个行号真的很烦噶试着写一个py去掉

2. 思路

def second_of_str分割，取分隔符右边的元素返回一个列表
def move传入文件路径，读取每行，列表存储，调用 second_of_str分割后的存入新列表
主函数调用move

3. 代码

				?

									def second_of_str(str,splitsymbol):

									    s = str.split(splitsymbol,1)   # 分隔符右边的元素

									    # if  len(s) == 1:

									    #     return []

									    return s[1]

									def move(file_path, new_file_path):

									    with open(file_path,encoding='utf-8') as f:

									        content = f.read().splitlines()

									    # for line in content:

									    #     print(line)

									    new_content = []

									    for line in content:

									        new_line = second_of_str(line,'.')

									        # 去掉后的每行加入新列表

									        new_content.append(new_line)

									    for line in new_content:

									        print(line)

									    f1 = open(new_file_path,encoding='utf-8',mode = 'w')

									    for line in new_content:

									        f1.writelines(line)

									        f1.writelines(["\n"])

									    f1.close()

									    return new_content

									if __name__ == '__main__':

									    f = move('1.txt','2.txt')
