Question

我在那里有五个琴弦：

    proc send_command_to_SSH {ssh_stream_id command} {
        while {1} {
            #tried to use this flush even here
            flush stdout    
            puts $ssh_stream_id "$command"
            #tried here also
            flush $ssh_stream_id
            flush stdout

            set L [gets $ssh_stream_id OutPut]
                if {$OutPut != ""} {
                    puts "$OutPut \n"
                    incr number_of_lines_sent_to_xsl 1
                    if {[regexp ".*194:" $OutPut]== 1} {
                    return "Done"
                      }

                    }

            }



         }

To execute the above procs I am executing the following commands: 
set a [open_ssh_connection]
set b [send_command_to_SSH $a "stack_mgr_cli" "xsl" 2]
set c [send_command_to_SSH $a "exit" "xsl" 2]

the output of "set a [open_ssh_connection]" is:
file38900e0

the output of "set b [send_command_to_SSH $a "stack_mgr_cli" "xsl" 2]" is:

More commands: 
stack_mgr --help 
stack_mgr@ip-172-32-43-194:~$  
16
(Call Generator) 53 %  Just as expected .

 The output of "set c [send_command_to_SSH $a "exit"]""
 expected : send command "exit" to the shell , and exit the above process.

 actual : (Call Generator) 53 % set c [send_command_to_SSH $a "exit"]
 $ $ stack_mgr_cli 

 -su: stack_mgr_cli: command not found 

  stack_mgr@ip-172-32-43-194:~$

如何提取字符串列表中的这些数字？

Answer 1

使用map函数（在Python 2.x中）：
https://docs.python.org/2/library/functions.html#map

some_ids = [1, 2, 3, 4, 5] 
string_list = map(str, some_ids)

或者在Python 3中，您需要将结果从map转换为列表： https://docs.python.org/3/library/functions.html#map

string_list = list(map(str, some_ids))

蟒蛇。如何从列表中的多个字符串行中提取数字？
