Printing lists in python without spaces

Question

I am doing a program that changes a number in base 10 to base 7, so i did this :

num = int(raw_input(\"\"))
mod = int(0)
list = []
while num> 0:
    mod =         


        

Answer 1

Use list_comprehension.

num= int(raw_input(""))
mod=int(0)
list =[]
while num> 0:
    mod=num%7
    num=num/7
    list.append(mod)
list.reverse()
print ''.join([str(list[i]) for i in range (0,len(list))])
