python 3.x - My program isn't sorting properly -

im making histogram file , got working not sorting them correctly. meaning 100 90 50 etc.

here code:

from collections import counter data=[] open("data.txt", 'r') f:     line in f:     line = line.strip()     data.append(str(line))  counts = counter(data)  key, size in sorted(counts.items()):     print('{}: {}'.format(key, int(size) * '*')) 

this output:

100: ****** 25: ** 50: *** 60: * 65: * 70: ** 75: * 80: **** 85: **** 90: *** 

any suggestions??

edit:

what mean go numerically in order. insted of 100, 25, 50, .... want 100, 90, 85,.....

njzk2 absolutely right, thanks! 1 way can :

... line = line.strip() # casting 'int' type before populating in data table.. data.append(int(line))  ... 

then, can

... # applying reversed reorder ascending order descending order. key, size in sorted(counts.items(), reverse=true): ...
