Question

I know how to control the number of decimals, but how do I control the number of zeros specifically?

For example:

104.06250000 -> 104.0625   
119.00000 -> 119.0  
72.000000 -> 72.0 

Answer 1

I don’t think there is a pre-defined format for this – format in python are inherited from C, and I am pretty sure you don’t have the desired format in C.

Now, in python 3, you have the format special function, where you can do your own formatting. Removing the last zeros in python is very easy: just use the strip method:

a = 1.23040000
print str(a).rstrip('0')

If you want to keep a 0 after the decimal point, that’s not very difficult either.
