自建一个模块 ¶

这里和视频有点差别，我自己写了另外一个模块，是计算五年复利本息的模块,代码如下：模块写好后保存在默认文件夹：balance.py

d=float(input('Please enter what is your initial balance: \n'))
p=float(input('Please input what is the interest rate (as a number): \n'))
d=float(d+d*(p/100))
year=1
while year<=5:
    d=float(d+d*p/100)
    print('Your new balance after year:',year,'is',d)
    year=year+1
print('your final year is',d)

调用自己的模块 ¶

新开一个脚本，import balance

import balance

""""
Please enter what is your initial balance:
50000  # 手动输入我的本金
Please input what is the interest rate (as a number):
2.3  #手动输入我的银行利息
Your new balance after year: 1 is 52326.45
Your new balance after year: 2 is 53529.95834999999
Your new balance after year: 3 is 54761.14739204999
Your new balance after year: 4 is 56020.653782067144
Your new balance after year: 5 is 57309.12881905469
your final year is 57309.12881905469
