Python – Range based programs

Multiplication tables in the given range:.

for n in range(5, 11):         for i in range(1,11):         print(n,’*’,i,’=’,n*i)

Factorials in the Given range:

for n in range(1,8):       fact=1     for i in range(1,n+1):         fact=fact*i     print(“factorial of”,n,”is”,fact)

Prime numbers in given range:

for n in range(1,51):       factors=0     for i in range(1,n+1):         if(n%i==0):             factors=factors+1       if(factors==2):         print(n,”is prime”)

Perfect numbers in given range:

for n in range(1,10000):       sum=0     for i in range(1,n):         if(n%i==0):             sum=sum+i       if(n==sum):         print(n,”is perfect”)
