Regex for number plus number sign in python

LetвЂ™s say the pattern youвЂ™re looking for is вЂњh.sвЂќ: this means any character ranging from a letter, a number, or a special character can be between the вЂњhвЂќ and the вЂњsвЂќ. Now letвЂ™s get into something special: we can actually use the period (.) to represent any character other than a newline character, which creates indentations. The two different applications of regular expressions are no different from entering a regular string. If youвЂ™re looking for a phrase, a part of a word, or a whole word such as вЂњwasвЂќ, then you can write exactly вЂњwasвЂќ. So letвЂ™s say youвЂ™re looking for occurrences of the letter вЂњeвЂќ: you can exactly write вЂњeвЂќ. Just like regular strings, the patterns always start and end with double quotations (вЂњвЂќ). LetвЂ™s go through some of the important meta-characters used to type out the patterns we need to look for. Also, when dealing with numbers, you will never deal with more than one digit at a time, since there isnвЂ™t a single character that represents anything beyond 0 through 9. The format of a phone number is a very specific pattern of numbers and hyphens and more than just a single character вЂ“ the general syntax of which weвЂ™ll discuss next.ДЇirst, it should be quickly noted that regex is generally case-sensitive: the letter вЂњaвЂќ and the letter вЂњAвЂќ would be considered to be separate characters. You could also look through text specifically for phone numbers (#-#-#).

On the other hand, in a string that read you could choose to look only for the letters within that string. This is the most basic application of regular expressions: you can look for only alphabetic characters in strings mixed with letters, numbers, and special characters.

For example, if you search for the letter вЂњfвЂќ in the sentence вЂњFor the love of all that is good, finish the job,вЂќ the goal is to look for occurrences of the character вЂњfвЂќ in the sentence.

This concept can apply to simple words, phone numbers, email addresses, or any other number of patterns. In fact, REGEX is actually just short for regular expressions, which refer to the pattern of characters used in a string. REGEX is a module used for regular expression matching in the Python programming language. Choosing between re.match and re.search.Using characters to create indentations.
