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

#the variable "tax" would now be: 34.46

x=12345.67890

# %x.yf - at least x long space (. and - included) for variable type float (f),
#         show y digits after .

print("x = %.2f" % x) #12345.67 <- show 2 digits after .
print("x = %2.2f" % x) #12345.67 <- 12345.67 takses more than 2 spaces
print("x = %10.2f" % x) #  12345.67 <- left 2 blank spaces before the number to match 10 long space
