Keep significant zeros using str(float) in python

Question

Considering the code below. The output of this is 2.76 but for the application I am using it for, the zero after 2.76 is significant thus I am searching for a way to output 2.760.

f = 2.7598
r = round(f,3)
s = str(r)
print(s)

Answer 1

You could remove the conversion to string and use simply use format():

f = 2.7598
r = round(f,3)
print(format(r, '.3f'))

Result:

2.760

Or if you need a string for whatever reason:

f = 2.7598
r = round(f,3)
s = format(r, '.3f')
print(s)
