Revision b268f797-b4ae-4760-8948-dca39fbcb71b - Code Golf Stack Exchange

**Python 2.7 - 152**

Unfortunately it fails for [September 1752][1]. Granted, it imports all of the calender functions, but only *uses* 1, and that just returns the start day of the week and the number of days.

 from calendar import*
 w,l=monthrange(*divmod(input(),100))
 print" Mo Tu We Th Fr Sa Su\n"+" "*w+''.join(["%3d"%s+"\n"*((s+w)%7<1)for s in range(1,l+1)])

Test output:

 > 198210
 Mo Tu We Th Fr Sa Su
 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
