Traceback (most recent call last):
File "", line 1, in
ValueError: list.index(x): x not in list

# file_1.py
a = 0
def funct_1() :
a = 1 # a is global
print(a)
# file_2.py

That's exactly what I did before and got "IndexError: list index out of range".
So, I thought my lambda was wrong and posted here.
Now, having seen
