Python 文件操作、异常处理及相关应用详解

1. 扑克牌手牌计数功能函数

我们先来看用于计算扑克牌手牌概率的 compute 函数，代码如下：

def compute(file str):
    while True:
        try:
            poker file = open(file str,'r')
            break
        except IOError:
            print("Error opening file:",file str)
            file str = input("Enter a file name: ")
    total count = 0
    nothing count = 0
    pair count = 0
    two pair count = 0
    three of a kind count = 0
    straight count = 0
    flush count = 0
    full house count = 0
    four of a kind count = 0
    straight flush count = 0
    royal flush count = 0
    for line str in poker file:
        total count = total count + 1
        fields = line str.split(',')
        hand rank str = field
