I have a quick question in terms of decimals points in Python 2. Here is the code in Python 2:
a = 1500/1589
print (round(a,2))
#0.0
I thought it would print out a = 0.94 as it did in Python 3. I am just wondering how I could get 2 decimals for my answer.
You need to specify that at least one of the inputs to the division is a floating point number by adding an explicit decimal point.
a = 1500. / 1589
print round(a, 2)
# 0.94
If you do not do this, both 1500 and 1589 are treated as integers and the result of 1500/1589 is required to be an integer (0) as well
1500 / 1589
# 0
print round(1500 / 1589, 2)
# 0.0
As a side note, if you want to print a number with two decimal places, a far easier method is to create a formatted string:
print '%0.2f' % (1500. / 1589)
# 0.94
print '{:.2}'.format(1500. / 1589)
# 0.94
That's because you're making an integer division. For instance do:
a = 1500.0/1589.0
print round(a,2)
Or if you have integers as input:
a = float(1500)/float(1589)
print round(a,2)
