printing all variables

[Sheldon]

Good day,

I would like to know if there is a way to print all the variables set
in a python program with having to write
"print variable" on all?

sincerely,
Sheldon

Not all the variables in a program (that would be rather more than you
want), but you can print all the variables in a specific namespace easily
enough:
[color=blue][color=green][color=darkred]
>>> from pprint import pprint
>>> def f(x):[/color][/color][/color]
pprint(locals() )

[color=blue][color=green][color=darkred]
>>> f(2)[/color][/color][/color]
{'x': 2}[color=blue][color=green][color=darkred]
>>> pprint(globals( ))[/color][/color][/color]
{'__builtins__' : <module '__builtin__' (built-in)>,
'__doc__': None,
'__name__': '__main__',
'f': <function f at 0x00B45B30>,
'pprint': <function pprint at 0x00B45BB0>}[color=blue][color=green][color=darkred]
>>> class C:[/color][/color][/color]
classvar = []
def __init__(self, n):
self.n = n

[color=blue][color=green][color=darkred]
>>> c = C(3)
>>> pprint(vars(c))[/color][/color][/color]
{'n': 3}[color=blue][color=green][color=darkred]
>>> pprint(vars(C))[/color][/color][/color]
{'__doc__': None,
'__init__': <function __init__ at 0x00B4A070>,
'__module__': '__main__',
'classvar': []}[color=blue][color=green][color=darkred]
>>>[/color][/color][/color]
