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
