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

Take a look at sys.stdout. It's a file object, wrapping standard output. As every file it has write method, which takes string, and puts it directly to STDOUT. It also doesn't alter nor add any characters on it's own, so it's handy when you need to fully control your output.

>>> import sys
>>> for n in range(8):
...     sys.stdout.write(str(n))
01234567>>> 

Note two things

• you have to pass string to the function.
• you don't get newline after printing.

Also, it's handy to know that the construct you used:

for i in range (0,len(list)):
   print list[i],

is equivalent to (frankly a bit more efficient):

for i in list:
    print i,
