Python 打印 while 循环的每次迭代

Question

我创建了一个求和函数，它接受一个开始编号和一个结束编号，并返回这两点之间的总和答案

def print_sum_equations(start_number,end_number):
    
    mySum = 0 
    num = start_number

    while num <= end_number:
         mySum += num 
         num += 1  
    print (mySum)
    
print_sum_equations(3,5)

它返回 12，这是正确的，但是，我希望我的输出如下所示

3 + 4 + 5 = 12

而不是仅仅返回答案。我对 python 还是个新手，正在学习如何迭代 while 循环，因此感谢任何帮助

Answer 1

def print_sum_equations(start_number,end_number):
    
    vals = [i for i in range(start_number,end_number+1)]

    s = sum(vals)

    for ind,i in enumerate(vals):
        print(f'{i}',end='')
        if ind != end_number-start_number:
            print(' + ',end='')
        else:
            print(f' = {s}')

print_sum_equations(3,5)
