In Python 3, I write a simple command to accept an integer input from the user thus: x = int(input("Enter a number: ")) If I skip the int() part and simply use x = input("Enter a number: "), my input's datatype is a string, not an integer. I understand that. However, ...

2 for num in numbers: 3 if num%2 ==0: 4 print(str(num) + ' is an even number') 5 In the code above, how do we know which are the global namespaces? You can use globals() to find out. globals() is a built-in function that returns a dictionary of the current global...
Python vs JavaScript: comparison table Python vs JavaScript: when to use? As explained, Python and JavaScript can definitely complement each other in software development projects. However, in some particular applications, one might be more suitable than the other. On the one hand, JavaS...

above, let’s check how to do it correctly in this simple case, since this is actually a viable solution in applications where a race condition from time to time is acceptable, and because locking into a single instance is the foundation we’ll use for the distributed algorithm described ...
It should be possible to demonstrate the power of Lisp in one hour, not 100. If Lisp advocates refuse to do this, then we shouldn’t be surprised when these languages remain stuck near the bottom of the charts. 这要求太高了。如果 Lisp 语言如此伟大,那么应该可以用简洁实用的术语来...
Python excels as a language for beginners. Racket excels at LOP. In each case, because that’s what the language was designed to do. The distinction between domain-specific and general-purpose languages is permeable. For instance, Ruby started as a general-purpose language, but...
Hashable objects that compare equal must have the same hash value, meaning default hash() that returns 'id(self)' will not do. That is why Python automatically makes classes unhashable if you only implement eq(). class MyHashable: def __init__(self, a): self._a = copy.deepcopy(a) ...
