Python: use vars() function in a method

Question

my goal is to make a string into a variable inside a function.

normally, i can do something like this:
vars()["my_var"] = 10
print(my_var) # 10

but its become an error if i do it inside a method:

def func():
vars()["my_var"] = 10
print(my_var) #error. my_var is not defined

any help please?

Answer 1

Well, dynamic variables is not a good idea, since it makes you work with a namespace you have to use special access to. It means, that if you make a "low level" assign to a variable, you have to access it the same way.

def func():
vars()['my_var'] = 10
print(vars()['my_var'])

func()

will do the trick, but it is still a bad idea.
Note: vars() without an argument is equivalent to locals(), so mind the scope.
