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 = RawBalanceprint 'Enter monthly payment:',MonthlyPayment = float(raw_input())print '\t\tAmount\tRemaining'table = PrettyTable(['Pymt#','Paid','Balance'])table.add_row(['---','---','---------'])i = 0while Balance>0:if i==0:paid = 0.00elif i>0 and Balance>=MonthlyPayment:paid = MonthlyPaymentelse:paid = BalanceBalance = Balance-paidtable.add_row([i,'$%.2f' % paid,'$%.2f' % Balance])i+=1table.sort_key(i)table.reversesort=Falsetable.border = 0print table
