Getting only 1 decimal place

Question

How do I convert 45.34531 to 45.3?

||

Answer 1

Are you trying to represent it with only one digit:

print("{:.1f}".format(number)) # Python3
print "%.1f" % number          # Python2

or actually round off the other decimal places?

round(number,1)

or even round strictly down?

math.floor(number*10)/10

'45.3'

Or use the builtin round:
