我已经开始编码大约一个星期了，在练习创建一个形状计算器时，我遇到了这样的错误:
Traceback (most recent call last):
File "python", line 4
if option = 'C':
^
SyntaxError: invalid syntax
代码如下:
print "The Calculator has been launched"
option = raw_input ("What shape is your object? Enter C for circle or T
for Triangle.")
if option = 'C':
radius = float (raw_input ("What is the radius of your circle?") )
area_1 = 3.14159 * ( radius ** 2)
print area_1
elif option = 'T':
base = float (raw_input ("What is the base of the triangle?"))
height = float (raw_input ("What is the corresponding height of the
triangle?"))
area_2 = (base * height) * 1/2
print area
else :
print "Please, enter a valid shape"
如果有人能解释错误的原因，我将不胜感激。
谢谢!
请您参考如下方法:
比较时必须使用==。 = 仅用于赋值。
因此在您的示例中，该行应该是
if option == 'C':
