基础题代码如下：

a =10

b =3

c=a/b-a

print(c)

print(type(c))

c=a/b*a

print(c)

print(type(c))

c=0.1*a//b-a

print(c)

print(type(c))

c=a//b+a%b

print(c)

print(type(c))

基础题运算结果：

加分题代码如下：

for chicken in range(0,36): # number of chicken should be between 0 and 36

      for rabbit in range(0,36): # number of rabbit should be between 0 and 36

               if chicken + rabbit ==35 and chicken*2 + rabbit*4 == 94: # the total number of heads is 35 and the total number of foot should be 94

                    print ('number of chicken:')

                    print (chicken)

                    print ('number of rabbit:')

                    print (rabbit)

运算结果如下：

number of chicken:

23

number of rabbit:
