Need help step by step with nested loop

Question

m = 1
for x in [1,2,3]:
for y in [3,1,4]:
if x == y:
m = m * x
print (m)

Answer 1

#run this code and see output,, you can understand, if not then you can reply...

m = 1
for x in [1,2,3]:
print("x =",x)
for y in [3,1,4]:
print(" y =",y)
if x == y:
m = m * x
print(" x==y, m=m*x:",m//x,'*',x,"=>m =",m)
print(m)

Answer 2

Jayakrishna🇮🇳 ☺️
#Now even I didn't understand ☺️ Try this:

m = 1
for x in [1,2,3]:
for y in [3,1,4]:
print(f"{x}=={y}",x==y)
if x == y:
print(f"\t\t m={m}*{x}")
m = m * x

print("print",m)

Answer 3

Great explanation! I got it. Thank you so much!

#message sending failed.

#Arti Kohli so adding here..
m = 0
for x in range (1,3):
k = 0
for y in range (-2,0):
k = k+y
m = m+k
print(m)
"""
for the code :
My solution is as follows:
output is -10 :

you have 2 loop , for x in range(1,3) outer loop runs for x = 1,2 and for every x value inner for y in range(-2,0) loop runs for y=-2,-1 ..
as follows :

for iteration x=1
m=0 #initially you set these m,k to 0

inner loop
k=0
for value y=-2
k = 0+ (-2)
k=-2
m=0+(-2)
m=-2
y=-1
k=-2+(-1)
k=-3
m=-2+ (-3)
m=-2-3
m=-5
inner loop end when y=0 now
next
for iteration x=2 now
and inner loop start again
k=0 #again set to 0

for value y=-2
k = 0+ (-2)
k=-2
m=-5+(-2)
m=-7
y=-1
k=-2+(-1)
k=-3
m=-7+ (-3)
m=-7-3
m=-10
