How to get the matching print?

[yunpengb]

Describe the bug
I make a test on win10, try to send a few commands and get their feedback printing.
code like this

import wexpect
import re

cmdPrompt = re.compile('[A-Z]\:.+>')
p = wexpect.spawn('cmd.exe')
p.expect(cmdPrompt, timeout = 50)

p.sendline('VER')
p.expect(cmdPrompt, timeout = 50)
print('========1 VER')
print(p.before)
print(p.after)

p.sendline('VOL')
p.expect(cmdPrompt, timeout = 50)
print('========2 VOL')
print(p.before)
print(p.after)

p.sendline('ECHO 1')
p.expect(cmdPrompt, timeout = 50)
print('========3 ECHO 1')
print(p.before)
print(p.after)

To Reproduce
run this script on win10

Expected behavior
every step send the command, I can get the matching feedback printing

Screenshots
Now seems the feedback printing is always to be showing later
The execution results are as follows

D:\CODE>python test.py
========1 VER
D:\CODE>
========2 VOL
VER

Microsoft Windows [Version 10.0.18363.1110]

D:\CODE>
========3 ECHO 1

D:\CODE>
D:\CODE>

Environment:

• [windows version] win10 10.0.18363.1110
• [Python version] Python 3.8.5
• [wexpect version] wexpect 4.0.0

I cannot reproduce:

D:\wexpect_test>python i41.py
========1 VER
VER

Microsoft Windows [Version 10.0.19041.508]


D:\wexpect_test>
========2 VOL
VOL
 Volume in drive D is DATA
 Volume Serial Number is 1234-5678


D:\wexpect_test>
========3 ECHO 1
ECHO 1
1


D:\wexpect_test>

D:\wexpect_test>

It seems that the cmdPrompt matches something else in your system.

Please try to replace the re.compile('[A-Z]\:.+>') expression to your exact prompt: cmdPrompt='D:\\CODE>'
