this time the program has to calculate the factorial (n!) of a non-negative number given by the user.<\/strong><\/p>\n

first we have to understand what factorial is. it is the multiplication of all the numbers from 1 to n.<\/strong><\/p>\n

n!= 1x2x3x4x5x. . . . . xn!<\/strong><\/p>\n

now we could use the python function for factorial  math.factorial(n) but lets do math.<\/span><\/strong><\/p>\n

first ask the user for a positive integer and set the folowing variables:<\/span><\/strong><\/p>\n

n = int(input())<\/span><\/strong><\/p>\n

f = 0  – – – – this is a counter<\/span><\/strong><\/p>\n

c = 1   – – – – this will be the factorial product<\/span><\/strong><\/p>\n

now we can do this with a while or a for loop, for the while loop we could put it like this:<\/span><\/strong><\/p>\n

while f < n:<\/span><\/strong><\/p>\n

       f += 1<\/span><\/strong><\/p>\n

       c = c*f<\/span><\/strong><\/p>\n

and the for loop:<\/strong><\/span><\/span><\/p>\n

for t in n:<\/strong><\/span><\/span><\/p>\n

        f += 1<\/span><\/strong><\/p>\n

       c = c*f<\/span><\/strong><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
