AttributeError in the kernel when modifying `locals` #19145

Closed BasSandor closed 2 years ago

BasSandor commented 2 years ago

Description

What steps will reproduce the problem?

I run a function in a seperate script. The function natively runs with magic numbers hard-coded into the functions. However, the functiona accepts **kwargs such that the locals() function may be altered using locals().update(). For example:

def func(**kwargs):
    a = b
    locals().update(kwargs)

Now, in the external script we run:

def main():
    func(a = c)

The problem occurs when I try to debug this file and when I manually map c to a using 

locals().update({a:c}).

Hey @BasSandor, thanks for reporting. We'll try to fix this bug in our next version after 5.3.3, to be released in mid-October. In the meantime, please stop modifying locals or you'll keep getting the same error.
