Python采用raw_input读取输入值的方法

本文较为详细的介绍了python中raw_input的用法，使用raw_input 能够很方便的丛控制台读入数据。具体用法示例如下：

1.输入字符串

    #13222319810101****
    nID = ''
    while 1:
      nID = raw_input("Input your id plz")
      if len(nID) != len("13222319810101****"):
        print 'wring length of id,input again'
      else:
        break

    print 'your id is %s' % (nID)

2.输入整数

    nAge = int(raw_input("input your age plz:\n"))
    if nAge > 0 and nAge < 120:
      print 'thanks!'
    else:
      print 'bad age'
    print 'your age is %d\n' % nAge

3.输入浮点型

    fWeight = 0.0
    fWeight = float(raw_input("input your weight\n"))
    print 'your weight is %f' % fWeight

4.输入16进制数据

    nHex = int(raw_input('input hex value(like 0x20):\n'),16)
    print 'nHex = %x,nOct = %d\n' %(nHex,nHex)

5.输入8进制数据

    nOct = int(raw_input('input oct value(like 020):\n'),8)
    print 'nOct = %o,nDec = %d\n' % (nOct,nOct)

本文示例对Python初学者有一定的学习借鉴价值，感兴趣的读者可以动手调试运行一下本文示例，以加深对raw_input用法的认识。
