Write a function called checkingIfIn that takes three parameters. The first is a required parameter, which should be a string. The second is an optional parameter called direction with a default value of True. The third is an optional parameter called d that has a default value of {‘apple’: 2, ‘pear’: 1, ‘fruit’: 19, ‘orange’: 5, ‘banana’: 3, ‘grapes’: 2, ‘watermelon’: 7}. Write the function checkingIfIn so that when the second parameter is True, it checks to see if the first parameter is a key in the third parameter; if it is, return True, otherwise return False.
But if the second paramter is False, then the function should check to see if the first parameter is not a key of the third. If it’s not, the function should return True in this case, and if it is, it should return False.
def checkingIfIn( x, direction = True , d = {
'apple': 2, 'pear': 1, 'fruit': 19, 'orange': 5, 'banana': 3, 'grapes': 2, 'watermelon': 7<

编写一个名为checkingIfIn的函数,接受三个参数。第一个参数为必需的字符串,第二个参数为可选布尔值,默认为True,第三个参数为可选字典,默认值为{'apple': 2, 'pear': 1, ...}。当第二个参数为True时,检查第一个参数是否为第三个参数的键,如果为键返回True,否则返回False。当第二个参数为False时,检查第一个参数是否不是第三个参数的键,如果不是则返回True,如果是则返回False。此外,编写一个test函数,根据布尔参数来检查整数是否为字典的键并返回对应值或False。"
