how to only show 1 decimal in a float code example

Example 1: how to print a float with only 2 digits after decimal in python

#to round floats in Python you can use the "round" function. ex:

tax = 34.4563
tax = round(tax, 2)

#the number 2 at the end is how many digits are rounded.

#the variable "tax" would now be: 34.46

Example 2: how to get number after decimal point

decnm = "0"+str(number-int(number))[1:]
float(decnm)
