computing the factorial of N

[prog92]

Your flow chart looks correct, though most factorial functions I've seen have started at N and worked down to 1, but this really only matters if you want to expand the program to tackle problems like dividing factorials.

Going through your flowchart:

READ N
Assuming you're using Python3 and are getting user input, this would be:
N = input("N: ")

M=1, F=1
Put those on separate lines, but otherwise that's exactly the right notation

F = F*M
Also correct notation, though you need to start a loop before this, since this step will be repeated for each value M

IS M = N?
IF YES, PRINT F -END
IF NO, M = M+1
This is a simple If statement. They use the following format:
if x:
   do this thing
else:
   do this other thing

In this case:
if M == N:
   print("Factorial = " + str(F))
   break loop (possibly by changing variable or break statement)
else:
   M += 1

The end code with the loop would be this:

N = input("N: ")

M = 1
F = 1

counting = True
while counting:
   F = F * M
   if M == N:
       print("Factorial = " + str(F))
       counting = False
   else:
       M += 1
