Python: 1 to 100 using While statement in 10 rows

I am trying to print 1 to 100 using while statement. Well, that is easy

 n =100
 i=0
 while i<n:
      i=i+1
      print (i)

But the problem is how to put 1 to 10 in a row, 11 to 20 in a row, and finally to 91 to 100 in a row. Could you tell me the way?

 x=1
    while x<101:
        if x%10==0:
            print(" {}{}".format(x,"\n"),end="" )
        else:
            print(" {}".format(x),end="")
            
        x+=1   

output:

 1 2 3 4 5 6 7 8 9 10
 11 12 13 14 15 16 17 18 19 20
 21 22 23 24 25 26 27 28 29 30
 31 32 33 34 35 36 37 38 39 40
 41 42 43 44 45 46 47 48 49 50
 51 52 53 54 55 56 57 58 59 60
 61 62 63 64 65 66 67 68 69 70
 71 72 73 74 75 76 77 78 79 80
 81 82 83 84 85 86 87 88 89 90
 91 92 93 94 95 96 97 98 99 100

print numbers from 100 to 0 with one loop

for i in range(100,-1,-1):
    if i%10==0 and i!=100:
        print(i)
    else:
        print(i,end=", ")

output:

100, 99, 98, 97, 96, 95, 94, 93, 92, 91, 90

89, 88, 87, 86, 85, 84, 83, 82, 81, 80

79, 78, 77, 76, 75, 74, 73, 72, 71, 70

69, 68, 67, 66, 65, 64, 63, 62, 61, 60

59, 58, 57, 56, 55, 54, 53, 52, 51, 50

49, 48, 47, 46, 45, 44, 43, 42, 41, 40

39, 38, 37, 36, 35, 34, 33, 32, 31, 30

29, 28, 27, 26, 25, 24, 23, 22, 21, 20

19, 18, 17, 16, 15, 14, 13, 12, 11, 10

9, 8, 7, 6, 5, 4, 3, 2, 1, 0

You can use zip and iter:

lst = [i for i in zip(*[iter(range(1,101))]*10)]

Change the last number to the size of the chunks you want; in this case it is 10.

Output:

>>> lst
[(1, 2, 3, 4, 5, 6, 7, 8, 9, 10), (11, 12, 13, 14, 15, 16, 17, 18, 19, 20), (21, 22, 23, 24, 25, 26, 27, 28, 29, 30), (31, 32, 33, 34, 35, 36, 37, 38, 39, 40), (41, 42, 43, 44, 45, 46, 47, 48, 49, 50), (51, 52, 53, 54, 55, 56, 57, 58, 59, 60), (61, 62, 63, 64, 65, 66, 67, 68, 69, 70), (71, 72, 73, 74, 75, 76, 77, 78, 79, 80), (81, 82, 83, 84, 85, 86, 87, 88, 89, 90), (91, 92, 93, 94, 95, 96, 97, 98, 99, 100)]

Then print each number inside the list:

for i in lst:
    for j in i:
        print(j, end=" ")
    print()

Output:

1 2 3 4 5 6 7 8 9 10 
11 12 13 14 15 16 17 18 19 20 
21 22 23 24 25 26 27 28 29 30 
31 32 33 34 35 36 37 38 39 40 
41 42 43 44 45 46 47 48 49 50 
51 52 53 54 55 56 57 58 59 60 
61 62 63 64 65 66 67 68 69 70 
71 72 73 74 75 76 77 78 79 80 
81 82 83 84 85 86 87 88 89 90 
91 92 93 94 95 96 97 98 99 100 

So overall you have:

lst = [i for i in zip(*[iter(range(1,101))]*10)]

for i in lst:
    for j in i:
        print(j, end=" ")
    print()

EDIT:

As someone mentioned this only works in python 3. It can be done in python 2 by simply changing end=" " to ,:

lst = [i for i in zip(*[iter(range(1,101))]*10)]

for i in lst:
    for j in i:
        print j,
    print

EDIT 2:

To do this with a while loop:

counter = 1
n = 100

while counter < n+1:

    if counter % 10 == 0:
        print(counter)
    else:
        print(counter, end=" ") #Change this line to print counter, for python version 2
    counter += 1

Your code is false. i is not I. indent is false too

def print_numbers(min_nu, max_nu, step):
   import sys
   if sys.version_info > (3,0):
      my_xrange = range
   else:
      my_xrange = xrange
   for i in my_xrange(min_nu, max_nu, step):
      buff = [str(j) for j in my_xrange(i, i + step)]
      print(" ".join(buff))

print_numbers(1, 100, 10)

You were pretty close, you were missing an if statement and changing the end for the print statement to " " as the default is '\n'.

print(*objects, sep=' ', end='\n', file=sys.stdout, flush=False)

N = 20
I = 1
while I <= N:
    if I % 10 > 0:
        print(I, end = " ")
    else:
        print(I)
    I += 1

1 2 3 4 5 6 7 8 9 10
11 12 13 14 15 16 17 18 19 20

Note: I += 1 in python is simpler than doing I=I+1. Also works for multiplication.

Python 2.x

The previous code works for Python 3.x as mentioned in the comments by @idjaw. For python 2.x, to use print as a function rather than a statement (i.e. print()) the followring needs to be imported at the start of the script.

from __future__ import print_function

A double nested for loop should do the trick for u:

>>> for i in range(1,101,10):
        for j in range(i, i+10):
            print(j, end=' ')
        print()


1 2 3 4 5 6 7 8 9 10 
11 12 13 14 15 16 17 18 19 20 
21 22 23 24 25 26 27 28 29 30 
31 32 33 34 35 36 37 38 39 40 
41 42 43 44 45 46 47 48 49 50 
51 52 53 54 55 56 57 58 59 60 
61 62 63 64 65 66 67 68 69 70 
71 72 73 74 75 76 77 78 79 80 
81 82 83 84 85 86 87 88 89 90 
91 92 93 94 95 96 97 98 99 100 

Or only using while loop, if that's your requirement:

>>> i = j = 1
>>> 
>>> while i < 101:
        while j < i+10:
            print(j, end=' ')
            j += 1
        i += 10
        print()


1 2 3 4 5 6 7 8 9 10 
11 12 13 14 15 16 17 18 19 20 
21 22 23 24 25 26 27 28 29 30 
31 32 33 34 35 36 37 38 39 40 
41 42 43 44 45 46 47 48 49 50 
51 52 53 54 55 56 57 58 59 60 
61 62 63 64 65 66 67 68 69 70 
71 72 73 74 75 76 77 78 79 80 
81 82 83 84 85 86 87 88 89 90 
91 92 93 94 95 96 97 98 99 100

You can use this this should do the job:

def solution_01(n):
    index = 0
    row = ''
    while index <=n:
        index+=1
        row += ' '+str(index) 
        if index%10 == 0:
            print row
            row = ''

solution_01(100)

Gives the output:

 1 2 3 4 5 6 7 8 9 10
 11 12 13 14 15 16 17 18 19 20
 21 22 23 24 25 26 27 28 29 30
 31 32 33 34 35 36 37 38 39 40
 41 42 43 44 45 46 47 48 49 50
 51 52 53 54 55 56 57 58 59 60
 61 62 63 64 65 66 67 68 69 70
 71 72 73 74 75 76 77 78 79 80
 81 82 83 84 85 86 87 88 89 90
 91 92 93 94 95 96 97 98 99 100
