Look at the code below:
def f1(l):
l[0] = 'row'
l[1] = 'col'
return True
def f2():
l = [0,0]
f1(l)
print(l)
f2()
running the f2 function, prints l = ['row', 'col']. Why did this happen?
My Python version is 3.7.13

l = [0,0]because I didn't return the list fromf1. I think thatlcould be['row', 'col']in 2 situations: 1) When I've definedlglobally and 2) whenf1returns a list and inf2, I have this line:l = f1(l)
