python文件操作练习

    读取文件截取字符

def getAppointFile():
    # 打开文件
    f = open(r'D:\test.txt', encoding='utf-8')
    # 读取文件一行
    content = f.readlines()
    for i in content:
        # 以空格区分返回集合
        list = i.split()
        for t in list:
            # 截取以.com结尾的字符串
            if (t.endswith('.com')):
                print(t)
    f.close()
