Python typeerrorfloatrequiredline.20

我今天心情不好。我已将您的代码修复为所需的功能。：）
主要是，您有多个错误。
1） 您的

elif

s的缩进错误。
2） 参数传递错误，

area=areaOfcircle（x）

3）

areaOfsquare（“正方形的长度是多少？”）

正在尝试传递字符串并计算字符串。
4） 在设计方面，在要求测量之前，您应该先要求用户输入形状。
5）

if shape==“Triangle”或“Triangle”：

应更改为

if shape.lower（）==“Triangle”：

#Python program when involved with maths
import math

def areaOfcircle(x):
#Calculate the area
    area=(math.pi)*math.pow(x,2)
    print(area,"is the area of your circle")
#Input used to find x
areaOfcircle(int(input("What is the radius of your circle?")))

def areaOftriangle(b,h):
    area=(b+h)/2
    print(area,"is the area of your triangle")

areaOftriangle(int(input("What is the base of your triangle")),int(input("What is the hight of your triangle")))

def areaOfsquare(x):
    area=math.pow(x,2)
    print(area,"is the area of your square")

areaOfsquare("What is the length of your square?")

flag="f"
while flag=="f":
    shape=input("Which of the following shapes, Circle, Triangle or Square do you want to calculate the area of: ")
    if shape=="Triangle" or "triangle":
        area=areaOftriangle
        print(area)

elif shape=="Square" or "square":
    area=areaOfsqaure
    print(area)

elif shape=="Circle" or "circle":
    area=areaOfcircle(x)
    print(area)
