实际上是这样调用的 muffledcalculator.calc(a, expr) 这样self 就是a, python隐含地把a 传进方法从而替代了self, 就成了绑定的方法, 就可以执行了. 否则就是非绑定方法 python中的正负无穷: 负无穷:float(-inf) 正无穷:float(inf) 如:A=float(inf) python中的str(): >>>str(5) >>>'5' >>>A=[]...
这是python源码中,在set中查找某一个元素是否存在的实现函数。但是不同的是,set中元素的查找是通过hash来进行的,所以in set的时间复杂度只有差不多O(1)。 这里和很多人说的不太一样,很多人都说python中的set对象具有O(1)成员关系检查。那现在通过set源码的熟悉,可以知道O(1)其实是最优的情况下。因为在发生...

然后,我们使用set_index函数将’Name’列设置为索引,并将inplace参数设置为True。结果输出了修改后的DataFrame对象,其中’Name’列成为了索引。 6. 总结 通过本文,我们了解了在Python中set_index函数中的inplace参数的作用。set_index函数可以将DataFrame中的一列或多列设置为索引,而inplace参数可以控制是否原地修改Data...
