猴子學Python - Business Computing in Python (week 2)

This series are notes taken for the coursera course: Programming for Business Computing in Python(1)(用Python做商管程式設計)

Week 1 is just an introduction about how computing can work for business management.

1. print and arithmetic

   • some terms
     statement, one statement must be put in a single line in python!
     operation
     function
     operand(argument)

   • “” or ‘’

   • change line with “newline character”: \n

   • And some other special characters: \t, \, ', "

   • string operation

   • arithmetic: +, -, *, **(square), /(floating-point division), //(floor division), %(remainder)

2. input and variables

   • variables:

     • takes a memory space
     • data type: int(integer), float(fractional numbers), string(string)
     • type, name, value
     • declare the value
     • use type() to see the type

   • string, integer and floating point

     • adding
     • type conversion int(), str()

EX1:

w = int(input())
x = int(input())
y = int(input())
z = int(input())
print(w*50 + x*10 + y*5 + z*1)

EX2:(My solution looks stupid…… )

a = int(input("Total:"))
change = 1000-a

FHbill = change//500

leftFH = change-FHbill*500
OHbill = leftFH//100

leftOH = leftFH-OHbill*100
FTbill = leftOH//50

leftFT = leftOH-FTbill*50
TENcoin = leftFT//10

leftTEN = leftFT-TENcoin*10
FIVEcoin = leftTEN//5

leftFIVE = leftTEN-FIVEcoin*5
ONEcoin = leftFIVE

print(FHbill, OHbill, FTbill, TENcoin, FIVEcoin, ONEcoin)
