python_表格形式輸出

1. 安裝prettytable模塊 pip install prettytable

在Pycharm中的解釋器中調用該模塊的話，需要在該IDE環境下的terminal里安裝，在外部運行py文件的話需要另外再安裝一次，因為兩者的路徑不一致

from prettytable import Prettytable

2. 代碼實例 

def FinanceCalculator():
    '輸入初始金額和月開銷數，返回剩下的金額、當月的支出數、和最后的支出數'
    print 'Enter opening balance:',
    RawBalance = float(raw_input())
    Balance = RawBalance
    print 'Enter monthly payment:',
    MonthlyPayment = float(raw_input())

    print '\t\tAmount\tRemaining'
    table = PrettyTable(['Pymt#','Paid','Balance'])
    table.add_row(['---','---','---------'])
    i = 0
    while Balance>0:
        if i==0:
            paid = 0.00
        elif i>0 and Balance>=MonthlyPayment:
            paid = MonthlyPayment
        else:
            paid = Balance
        Balance = Balance-paid
        table.add_row([i,'$%.2f' % paid,'$%.2f' % Balance])
        i+=1
    table.sort_key(i)
    table.reversesort=False
    table.border = 0
    print table
