Help me to minimize this python code.

Question

I'm made one program for print all paper size by using only A0 paper size.
please help me to make it sort. Please check the code in my profile.

# for A0 size ppr
a0_lenght=1189
a0_breath=841
print('A0 size=',a0_lenght,'mm x',a0_breath,'mm')

# for A1 size ppr
max1=max(a0_lenght,a0_breath)
a1_lenght=int(a0_breath)
a1_breath=int(max1/2)
print('A1 size=',a1_lenght,'mm x',a1_breath,'mm')

# for A2 size ppr
max2=max(a1_lenght,a1_breath)
a2_lenght=int(a1_breath)
a2_breath=int(max2/2)
print('A2 size=',a2_lenght,'mm x',a2_breath,'mm')

# for A3 size ppr
max3=max(a2_lenght,a2_breath)
a3_lenght=int(a2_breath)
a3_breath=int(max3/2)
print('A3 size=',a3_lenght,'mm x',a3_breath,'mm')

# for A4 size ppr
max4=max(a3_lenght,a3_breath)
a4_lenght=int(a3_breath)
a4_breath=int(max4/2)
print('A4 size=',a4_lenght,'mm x',a4_breath,'mm')

# for A5 size ppr
max5=max(a4_lenght,a4_breath)
a5_lenght=int(a4_breath)
a5_breath=int(max5/2)
print('A5 size=',a5_lenght,'mm x',a5_breath,'mm')

# for A6 size ppr
max6=max(a5_lenght,a5_breath)
a6_lenght=int(a5_breath)
a6_breath=int(max6/2)
print('A6 size=',a6_lenght,'mm x',a6_breath,'mm')

# for A7 size ppr
max7=max(a6_lenght,a6_breath)
a7_lenght=int(a6_breath)
a7_breath=int(max7/2)
print('A7 size=',a7_lenght,'mm x',a7_breath,'mm')

# for A8 size ppr
max8=max(a7_lenght,a7_breath)
a8_lenght=int(a7_breath)
a8_breath=int(max8/2)
print('A8 size=',a8_lenght,'mm x',a8_breath,'mm')

You can see this code in my profile also.

Answer 1

It can be shortened to

length=1189
breadth=841
for i in range(0, 8):
print('A',i,' size=',length,'mm ×',breadth,'mm')
length,breadth = breadth, int(max(length, breadth)/2)

Answer 2

To minimize (and for other reasons) you could put the values into a dictionary (see tutorials). The content of a dictionary is easy to sort (see tutorials).

Some languages have libraries with utils for that within their standard libraries, in other languages you have to implement a sort algorithm.
