为什么我的数据在使用split函数时没有转换为float类型#Python3

Question

u,p,k = float(input(" enter the values of viscoity, pressure , prmeability")).split(",")

l,A = int(input("enter the vaues of length and area").split(" "))


def flow_rate(u,p,k,l,A):

  Q=k* A * p/l*u

  print(f"the Q is {Q}")
flow_rate(u,p,k,l,A)

Answer 1

这是因为您不能在列表上调用int，而希望将值转换为int

input()         -> str       : "1 2 3"
input().split() -> list[str] : ["1", "2", "3"]

使用map

l,A = map(int, input("enter the vaues of length and area").split())

或者一份清单

l, A = [int(x) for x in input("enter the vaues of length and area").split()]
