python如果定义了函数,那么将变量输出写入文件的方式是什么?

正如Vinny提到的,这个例子既不完整也不可验证。我的最佳猜测是你想替换 mode='w+' 具有 mode='a' . 你好像没有在读 fileData ,所以不要为 + . 每次运行循环时,写入模式都会覆盖文件。

@调理灵魂,使用 str.format 方法并关闭 fileWrite.close() 在for循环之外。请在下面试试,它应该管用。

def ChkCon():
    Flag    = False
    FlagTcp = False
    NewStr  = ''
    OutStr  = ''
    HOST    = ''
    MARKER  = '----------------'
    NEWLINE = '\n'
    fileData = 'ldap_conn_logs'
    with open('ldap_bind_netstat', 'r') as log:
        for line in log:
            if '| SUCCESS |' in line:
                if Flag:
                    return HOST
                    return MARKER
                    return NewStr
            if '| SUCCESS |' in line:
                Flag = False
                FlagTcp = True
                HOST = line.split()[0]
                NewStr = ''
            elif 'FAILED' in line:
                FlagTcp = False
            elif 'UNREACHABLE' in line:
                FlagTcp = False
            if FlagTcp and line.startswith('tcp'):
                NewStr += line
                if 'tsdj-lb-oidc01' not in line:
                    Flag = True
                OutStr = HOST + NEWLINE + MARKER + NEWLINE + NewStr
                fileWrite = open(fileData, 'w')
                fileWrite.write(OutStr)
                file.write('{0}'.format(OutStr))
        fileWrite.close()
        log.close()
