We assign our specific regular expression pattern, "^([A-Za-z]{1,4})", to the "char_form" variable. This pattern signifies that the initial 4 characters should be either lowercase or uppercase letters. "char_renew" is initially set to an empty string. We employ an IF statement to im...

Python Regular Expresion with examples: A regular expression (or RE) specifies a set of strings that matches it; the functions in this module let you check if a particular string matches a given regular expression.

1 The syntax for regular-expression represents the content of a string literal that cannot include whitespace characters other than as the specific meaning of the whitespace character as a pattern character. Do not consider spaces or portions between syntax elements as allowing any form of whitespace...
wu is an expression which represents concatenating the value of u onto the end of the value of w. Similarly, waaaa would be the result of concatenating aaaa ont w, so waaaa = abcaaaa.Recall that I'm using the variable e to represent the empty string. You can concatenate th...

By default, a quantifier will match as much as possible of the target string, using what is referred to as a greedy algorithm. For example, the regular expression 'A.*A' matches the entire string 'ABACADA' because the substring between the required outer 'A' characters matches the ...
*The asterisk is a symbol-“repeater”.*means 0 or more occurrences of the preceding character or sub-expression. For instance, theabc*dpattern matchesabd,abcd,abccd, but notaorabcx. The.*pattern matches a string of any length (including the empty string) that does not contain the newline...
