We will freely use the term object regardless of whether the object has built-in or class type, is named or unnamed, or can be read or written. Initializer(初始值) initialization and assignment are different operations in C++ C++里变量初始化和赋值是不同的操作 Initialization is not assignment....
Expressing conditional logic as array operations xarr = np.array([1.1, 1.2, 1.3, 1.4, 1.5]) yarr = np.array([2.1, 2.2, 2.3, 2.4, 2.5]) cond = np.array([True, False, True, True, False]) print(xarr[~cond]) # 二者等价
but this time, the location isn't the one to fetch from--we're on the left-hand sign of an assignment operator, so*iptells us the location to store to. (The situation is no different from array subscripting expressions such asa[3]which we've already seen appearing on both sides of ...
You can access individual characters within aCStringobject with theGetAtandSetAtmember functions. You can also use the array element, or subscript, operator ([]) instead ofGetAtto get individual characters (this is similar to accessing array elements by index, as in standard C-style strings). ...
