I got the correct output but I can't make it print the columns side by side. How can I print as columns inside a for loop?

column = int(input("column: "))
Num1=1
Num2=1
Mult=0

for Num1 in range(1,10):
    for Num2 in range(1,column+1): 
        if Num1==1:
            print(1)
        else:
            Mult= Num1+Mult
            print(Mult)
    print(" ")
    Mult=0

A input of 3 gets me all values from 11 up to 93:

1
1
1

2
4
6

...

8
16
24

9
18
27

whereas I want them like so:

1   1   1
2   4   6
3   6   9
   ...
8  16  24
9  18  27

You can control what to put between several values (print(1,2,3,4, sep="#" ) using sep="#" and what to put at the end of the printed line with 'end='\n'.

Changing

print(1, end="   ")     # some space instead of \n

and

print(Mult, end="   ")  # after each column should work

in combination with the loops you got should get you started (see this answer for more in depth explanation or review the official documentation of print(*objects, sep=' ', end='\n', file=sys.stdout, flush=False) for details.

You can solve your task with some creative formatting, generator expressions, joining of generator decompositions in a single print statement:

rows_up_to_X_times = 12
columns_up_to_X = 12

max_width = len(str(rows_up_to_X_times * columns_up_to_X ))

# 99*99 max - need to adapt formatting otherwise
print(  *('  '.join((f"{b:2}*{a:2} = {a*b:{max_width}}" 
                      for a in range(1,rows_up_to_X_times+1)))
          for b in range(1,columns_up_to_X+1)), sep="\n")

Output:

 1* 1 =   1   1* 2 =   2   1* 3 =   3   1* 4 =   4  [...]   1*10 =  10   1*11 =  11   1*12 =  12
 2* 1 =   2   2* 2 =   4   2* 3 =   6   2* 4 =   8  [...]   2*10 =  20   2*11 =  22   2*12 =  24
 3* 1 =   3   3* 2 =   6   3* 3 =   9   3* 4 =  12  [...]   3*10 =  30   3*11 =  33   3*12 =  36
 4* 1 =   4   4* 2 =   8   4* 3 =  12   4* 4 =  16  [...]   4*10 =  40   4*11 =  44   4*12 =  48
 5* 1 =   5   5* 2 =  10   5* 3 =  15   5* 4 =  20  [...]   5*10 =  50   5*11 =  55   5*12 =  60
 6* 1 =   6   6* 2 =  12   6* 3 =  18   6* 4 =  24  [...]   6*10 =  60   6*11 =  66   6*12 =  72
 7* 1 =   7   7* 2 =  14   7* 3 =  21   7* 4 =  28  [...]   7*10 =  70   7*11 =  77   7*12 =  84
 8* 1 =   8   8* 2 =  16   8* 3 =  24   8* 4 =  32  [...]   8*10 =  80   8*11 =  88   8*12 =  96
 9* 1 =   9   9* 2 =  18   9* 3 =  27   9* 4 =  36  [...]   9*10 =  90   9*11 =  99   9*12 = 108
10* 1 =  10  10* 2 =  20  10* 3 =  30  10* 4 =  40  [...]  10*10 = 100  10*11 = 110  10*12 = 120
11* 1 =  11  11* 2 =  22  11* 3 =  33  11* 4 =  44  [...]  11*10 = 110  11*11 = 121  11*12 = 132
12* 1 =  12  12* 2 =  24  12* 3 =  36  12* 4 =  48  [...]  12*10 = 120  12*11 = 132  12*12 = 144
