If-else in for loop In this section, we will see how to use if-else statements with a loop. If-else is used when conditional iteration is needed. For example, print student names who got more than 80 percent. The if-else statement checks the condition and if the condition is True it...

As you can see in this code snippet, if you use an operator without the required operands, then you’ll get a syntax error. So, operators must be part of expressions, which you can build using Python objects as operands.So, what is an expression anyway? Python has simple and compound ...
if num % 2 == 0: print("Even") else: print("Odd") # Calling the function with different values check_even_odd(10) check_even_odd(15) Output: Explanation: Here, the function checks whether a number is even or odd by using the modulus operator. Here,15 and 10 are passed as argume...

In Python, you can specify an else statement to a for loop or a while loop. The else block is executed if a break statement is not used.
class ArrayList: def __init__(self, number_list): self.numbers = number_list def __iter__(self): self.pos = 0 return self def __next__(self): if(self.pos < len(self.numbers)): self.pos += 1 return self.numbers[self.pos - 1] else: raise StopIteration array_obj = ArrayList...
And what exactly is a process, anyway? In this section, you’ll answer these questions. You’ll come away with a high-level mental model for thinking about processes. If you’re already familiar with processes, then you might want to skip directly to basic usage of the Python subprocess ...
