Hello
What is the equivalent function of php isset() in python
try:
if variable:
# isset
pass
except NameError:
# not set
pass
you could use:
>>> 'variable' in vars()
But be aware that it is bad bad practice to do it like that.
If you need variables that you don't know that name of, you should put them in a dictionary. They are made for that exact purpose.
>>> unkown_vars = {}
>>> unkown_vars['variable'] = 42
>>> 'variable' in unkown_vars
True
