Vscode has an issue with the lambda expression when I create a function, it works until I either save the script or run the script then the code below get changed from this automatically
a = lambda user : user + 10
re = a(40)
print(re)
to this
def a(user): return user + 10
re = a(40)
print(re)
This is not a Vscode issue. It is due to pep8 auto formatting.(vscode is suggesting you the best way to write your code) Try to disable auto format in vscode. Go to File -> Preferences -> settings Look for python> Formatting autopep8 path and turn it to null or something. But I don't recommend to do that because according to pep8 :
"Always use a def statement instead of an assignment statement that binds a lambda expression directly to an identifie"
