The for statement in Python differs a bit from what you may be used to in C or Pascal. Rather than always iterating over an arithmetic progression of numbers (like in Pascal), or giving the user the ability to define both the iteration step and halting condition (as C), Python’s for...

If none of our if and elif statements return true, the default condition is else. Now let's look at a modified example where we use a function that checks to see if we can read the shadow file. We test this with the os.access method. We want to know if we can read the file, ...
Basic terms (class, function, conditional statements, loops, etc.) Now let’s move forward with conditional statements. The most basic conditional statement is “if.” The logic is simple, if the provided condition is it will execute the statement, else it will move on. Basic structure of ...
