How do I change from lowercase to uppercase in Perl?
The Perl string lc() function and uc() function are two basic functions that are easy to understand—they convert a string to all lowercase or all uppercase respectively. First, $orig_string is set to a value—in this case, This Test Is Capitalized. Then the lc() function is run on $orig_string.
Is Python better than Perl?
As seen above where both languages are good on their regard as per the applications they target, Python takes a bit of advantage over Perl as a first choice for a novice due to its clean and easy to understand code, whereas on other hand Perl outperforms Python when it comes to string manipulation operations and some …
How do I convert a string to all uppercase characters in Perl?

In particular, any code in an if (CONSTANT) block will be optimized away if the constant is false. As with all use directives, defining a constant happens at compile time.
Should module names be capitalized in Perl?

Other modules should begin with a capital letter and use mixed case, but probably without underscores due to limitations in primitive file systems’ representations of module names as files that must fit into a few sparse bytes.
