Python print numbers in one line without space

print[*range[1, int[input[]]+1], sep=''] 

This was the code I found in a discussion on hacker rank. But I did not understand it. Can anyone please explain this?

So, from what I can tell, this is how it works:

int[input[]]

This takes input from the user. Next;

range[1,...+1]

This creates a range from 1 to our number we inputted earlier. The +1 means that it will include the max number. And then:

print[*...,sep='']

The * sign, from what I can tell, just effectively returns each value in our range one to be printed. The sep='' just means each value is separated by '' or nothing.

Hope this is useful to you.

Ok so we have print function. Inside we have this strange *range[1, int[input[]]+1] this is range function which return value from 1 to n [n is typed in input] in a form of a range object. * unpack this object to form like: 1 2 3 4 ... with spaces, so we have this sep='', keyword argument that makes separation from space to '' [no separate between].
Also you can do it like that:

n = input["Type integer value: "]
try:
    [print[x+1,end=""] for x in range[int[n]]]
except ValueError:
    exit["Typed string not number"]

for i in range[0, 10]:
    print['*', end=""]
print["\n"]
	

**********

import functools
printf = functools.partial[print, end=""]
for i in range[0, 10]:
   printf['*']
   i = 0
	

**********

i=0;
while i>> import numpy as np
>>> res = list[np.cumsum[range[0,10,2]]]
>>> res
[ 0,  2,  6, 12, 20]
