python - 如何将一个数字除以索引中的一个数字？

Question

我的程序应该回答 ax = b 形式的方程

    a = input("What is the part with the variable? ")
    b = input("What is the answer? ")
    print('the equation is', a , '=', b)
    letter = a[-1]
    number = a[0:-1]
    answer = b /= number
    print(letter,"=",answer)

在第 6 行中，我收到无效语法错误。如何回答这个方程？

Answer 1

a = input("What is the part with the variable? ")
b = input("What is the answer? ")
print('the equation is', a , '=', b)
letter = a[-1]
number = a[0:-1]
answer =float(b)/float(number)
print(letter,"=",answer)

What is the part with the variable? 25c

What is the answer? 8

the equation is 25c = 8

c = 0.32
