自己的模块

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 """"

模块存储路径说明¶

在Mac系统中，下载的python模块会被存储到外部路径site-packages，同样，我们自己建的模块也可以放到这个路径，最后不会影响到自建模块的调用。
