I am going through the book lp3thw again from the start as I had taken some time off. I have come to ex5 and have been working on the study drills and I wanted to take the 2 converted values and have them displayed as a rounded number to 2 decimal places. After a bit of wading around in the documentation and using google I came across:
print(round(i,4))
Giving me the ability to round a float.
Great, this sounds like what I want to do. So I tried various ways of incorporating round
into the print
statement with no success. In the end I decided to just create variables called weight_kg_rounded
and height_cm_rounded
and just do the math in there and then print the rounded number.
What I eventually ended up with was this:
name = 'Graham Hand'
age = 39 #not a lie!
height = 74 #inches, lie!
height_cm = height * 2.54
height_cm_rounded = round(height_cm,2)
weight = 180 #lbs.....total lie
weight_kg = weight / 2.2
weight_kg_rounded = round(weight_kg,2)
eyes = 'Blue'
teeth = 'present'
hair = 'Grey'
print(f"Let's talk about {name}.")
print(f"He's {height} inches tall.")
print(f"He weigh's {weight} pounds.")
print("Actually, that's not too heavy")
print(f"He's got {eyes} eyes and {hair} hair.")
print(f"His teeth are all {teeth}.")
print(f"He is {height_cm} tall in centimetres")
print(f"He is {weight_kg_rounded} in kilograms")
#This line is tricky, try to get it exactly right.
total = age + height + weight
print(f"If I add {age}, {height}, and {weight} I get {total}")
This is me mucking around for my own curiosity, I realize it’s not exactly as the example in the book but there ya go.
Anyone have any other suggestions on how to do this?
