python_表格形式输出

1. 安装prettytable模块 pip install prettytable

在Pycharm中的解释器中调用该模块的话，需要在该IDE环境下的terminal里安装，在外部运行py文件的话需要另外再安装一次，因为两者的路径不一致

from prettytable import Prettytable

2. 代码实例 

def FinanceCalculator():
    '输入初始金额和月开销数，返回剩下的金额、当月的支出数、和最后的支出数'
    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
