Python 使用 if 语句验证多个值

Question

Example1 检查单个值:

def validate(self, data, check, col):
    output = []
    for key, value in data.iteritems():
        try:
            if value[col] == check:
                output.append("{},{},Passed".format(key,value[col]))
            else:
                output.append("{},{},Failed".format(key,value[col]))
        except IndexError as e:
            pass
    return output


data1 = {key1:['a','b','c','ok'], key2:['a','b','c','down']}
check = "ok"
col = 3
print self.validate(data1, check, col)

输出:

['key1','ok','Passed', 'key2','down','Failed']

Example2 检查两个值:

 data1 = {key1:['a','b','c','ok', "True"], key2:['a','b','c','down', "False"]}

 def validate(self, data, check1, check2, col1, col2):
    output = []
    for key, value in data.iteritems():
        try:
            if value[col1] == check1 and value[col2] == check2:
                output.append("{},{},{},Passed".format(key,value[col1], value[col2]))
            else:
                output.append("{},{},Failed".format(key,value[col1], value[col2]))
        except IndexError as e:
            pass
    return output

有没有一种方法可以在一个代码中实现上述两个示例(验证多个值一、二、三、四)

Answer 1

为什么不将 all 与列/检查值的压缩列表一起使用？

if all(value[col] == check for col,check in zip((col1,col2),(check1,check2))):

如果你有更多的参数，我建议你转:

def validate(self, data, check1, check2, col1, col2):

进入

def validate(self, data, check_values, columns):

所以你可以适应:

if all(value[col] == check for col,check in zip(columns,check_values)):

而且，由于这些值和列是链接的，因此可以直接传递元组列表或将它们链接在一起的字典以验证。
