从 Python 获取 Powershell 脚本的返回码

Question

EDITED to clean up the info:

I am writing a PowerShell script that will call another script.

Once I get the return code, I want to use it in an if statement:

MY CODE:

if ($LASTEXITCODE -eq $TRUE) {
# Start job.
} else {
# Send failed email
}

---

EDIT 2: Correct format as noted by: Ansgar Wiechers

**if ($LASTEXITCODE -eq 0)** {
# Start job.
} else {
# Send failed email
}

Answer 1

As @AnsgarWiechers mentioned, you should be explicitly testing for $LASTEXITCODE -eq 0 instead of $true .

Here's a simple snippet for your example:

test.py content:

import sys
print(f'Testing for {sys.argv}')
assert sys.argv[1] == 'Success'

test.ps1 content:

py test.py Fail # or Success
if ($LASTEXITCODE -eq 0) {
    Write-Output "Python script ran successfully"
}
else {
    Write-Output "Python script failed"
}

Results:

Testing for ['test.py', 'Success']
Python script ran successfully

# ...

Testing for ['test.py', 'Fail']
Traceback (most recent call last):
  File "test.py", line 5, in <module>
    assert sys.argv[1] == 'Success'
AssertionError
Python script failed
