In this case, 2.0 and 4.0 are floating-point numbers. 6.0 is also a floating point number. So far, you may notice that the result of an addition operation will have the same data type as the operands involved in the addition operation. But what happens when you add an integer to a fl...
Use thehyphen(-) before the number to make it a negative number. In other words, everything else is similar to a positive number. If we don't put ahyphen(-) before a number, then Python considers it as a positive integer. Let's see the addition example with negative integers. # neg...
For instance, the %s specifier is used as a placeholder for string variables. Similarly, the %d specifier is used as a placeholder for the integers. If we pass an integer at the place of the string variable or a string in place of the integer, the program will run into a TypeError exce...
bool---Boolean values True and False. NoneType---special and has one value, None can use type () to see the type of an object. can convert object of one type to another float (3) converts integer 3 to float 3.0. int (3.9) truncates float 3.9 to integer 3. 注:truncate的本意是截...
This helps Python ensure that you pass the right type to the function. In this case, the function signature is a pointer to an integer. ctypes will allow you to specify this using the following code: Python >>> add_one = add_lib.add_one >>> add_one.argtypes = [ctypes.POINTER(...
This particular algorithm has been devised to produce and present the Fibonacci series based on a designated number of iterations, which is represented as N. Start Step 1 → Take integer variables X, Y, Z Step 2 → Set X = 0, Y = 0 Step 3 → DISPLAY X, Y Step 4 → Z = X +...

Here's a fun project attempting to explain what exactly is happening under the hood for some counter-intuitive snippets and lesser-known features in Python.While some of the examples you see below may not be WTFs in the truest sense, but they'll reveal some of the interesting parts of ...
This expression contains several integer literals, which are themselves expressions evaluated immediately. The assignment statement assigns the object created by the list literal to the name numbers. This statement is not an expression and doesn’t return a value. However, it includes the list ...
