import random
m = 0
while m!="fim" :
n1=int(random.random()*10)
n2=int(random.random()*10)
m = raw_input("{} * {} = ".format(n1,n2))
mult = int(n1*n2)
if m==mult :
print "correto!"
else :
print "errado!!"
But whenever I type something, the program always prints "wrong !!" , What is the error in my code? Is it well written? Is it possible to optimize it more? If so, how?
Having some problems, besides comparing a string with a number, letting you enter text where you expect a number does not seem like a good idea. Of course you can handle the exception raised. It would not be a bad idea since it is a possible mistake. But for simplicity I prefer to just change the input that indicates the end.
The generated numbers were also wrong, it generated what I imagine is not what you want, since this seems to be a case of a table. If you really want 0, you can go back to 10 as you were.
import random
m = 1
while m != 0:
n1 = int(random.random() * 9) + 1
n2 = int(random.random() * 9) + 1
m = int(raw_input("{} * {} = ".format(n1, n2)))
print ("correto!" if m == n1 * n2 else "errado!!")
See working on ideone . And no Coding Ground . Also I put GitHub for future reference .
If you do type(m) and type(mult) you will see that the first is str while the second is int .
To solve, just modify if , doing a conversion of the variable m to integer:
if int(m)==mult :
print "correto!"
else :
print "errado!!"
