I’m solving some exercises in python and when I put the code this way:
A = float(input(""))
B = float(input(""))
C = float(input(""))
triangulo = float((A*C)/2)
circulo = float(3.14159*(C**2))
trapezio = float(((A + B)*C)/2)
quadrado = float(B*B)
retangulo = float(A*B)
print("TRIANGULO: %0.3f" %triangulo)
print("CIRCULO: %0.3f" %circulo)
print("TRAPEZIO: %0.3f" %trapezio)
print("QUADRADO: %0.3f" %quadrado)
print("RETANGULO: %0.3f" %retangulo)
Gives an error where it says it cannot convert string to float, right on the first line (A = float(input(""))). But seeing the answer, I realized that a correct way to do it would be:
valor = input().split(" ")
a, b, c = valor
pi = 3.14159
triangulo = (float(a) * float(c))/2
circulo = pi * (float(c)* float(c))
trapezio = float(c) *(float(a) + float(b)) / 2
quadrado = float(b) * float(b)
retangulo = float(a) * float(b)
print("TRIANGULO: %0.3f\nCIRCULO: %0.3f\nTRAPEZIO: %0.3f\nQUADRADO: %0.3f\nRETANGULO: %0.3f" % (triangulo, circulo, trapezio, quadrado, retangulo))
and wanted to understand the reason and meaning of valor = input().split(" ") in that code.
In the statement of the year it says that the entries will be informed in the same row, at once?

Say yes, that’s the purpose of the split?

Yes. When receiving on the same line you will receive the string
"1 2 3"(example) when usinginput(). Since there are multiple values, you divide the string into whitespace,split(' '), to get a list['1', '2', '3']and so I was able to convert to float.– Woss
nossaa, thank you so much!!!!

And instead of every time convert to
float, vc can do this only once at the beginning, like this: https://ideone.com/yYx8B5– hkotsubo
