what is difference between

Question

i=1
while i<=4
j=1
k=i=m
while j<=k
print(m)
m=m+1
j=j+1
print
i=i+1

and

i=1
while i<=4
j=1
k=i
while j<=k
print(m)
k=k+1
j=j+1
print
i=i+1

Answer 1

You should avoid to use such assignments 'k=i=m'. And 'm' is not defined. The first example needs a value for 'm' to work.
In the second example your inner loop is infinite.

Answer 2

Your first loop has more errors. M isn't defined. your missing : in 4 places. Your loops are infinite.
