EXAMPLE:
print(r'\tTab')
note: will ignore backslashes ()
Compile Method pattern = re.compile(r'abc')
matches = pattern.finditer(text_to_search)
for match in matches: print(match)

-->RETURNS: <_sre.SRE_Match object; span=(1,4), match='abc'> span=(beginning of match,end of match)
String Slicing EXAMPLE: text_to_search[1:4] RETURNS: text from characters 1 to 3

EXAMPLE SEARCH FOR PHONE NUMBER pattern = re.compile(r'\d\d\d.\d\d\d.\d\d\d\d')
matches = pattern.finditer(text_to_search) for match in matches: print(match)
RETURNS: <_sre.SRE_Match object; span=(00,00), match='000-000-0000'>
USE A CHARACTER SET use brackets to specify characters to search for [] pattern = re.compile(r'\d\d\d[-.]\d\d\d[-.]\d\d\d\d')
matches = pattern.finditer(text_to_search) for match in matches: print(match)
RETURNS:
<_sre.SRE_Match object; span=(00,00), match='000-000-0000'>
NOTE:
will only return phone numbers with a - or . At that point in expression.

EXAMPLE 2:
pattern = re.compile(r'[89]00[-.]\d\d\d[-.]\d\d\d\d')
RETURN NOTE: only match 800 or 900 numbers at beginning
USE A CHARACTER SET WITH RANGE use brackets to specify characters to search for [0-9] or [a-c] EXAMPLE 1:
pattern = re.compile(r'[0-5]')
RETURN NOTE:
only match any number between 0 and 5

EXAMPLE 2:
pattern = re.compile(r'[a-z]')
RETURN NOTE: only match any letter between a and z

EXAMPLE 3:
pattern = re.compile(r'[a-zA-Z]')
RETURN NOTE: only match any letter between a and z or between A and Z

EXAMPLE 4: NEGATE ^
pattern = re.compile(r'^[a-zA-Z]')
RETURN NOTE: only match any letter that is NOT between a and z or between A and Z
USE QUANTIFIERS ***** - 0 or More + - 1 or More ? - 0 or One {3} - Exact Number {3,4} - Range of Numbers (Minimum, Maximum) EXAMPLE 1:
pattern = re.compile(r'**\d**{3}**.\d**{3}**.\d**{4}')
RETURN NOTE: only match 3-digits, any character, 3-digits, any character, 4-digits

EXAMPLE 2:
pattern = re.compile(r'**Mr\.**?**\s[A-Z]\w***')
RETURN NOTE: only matches 'MR' then 0 or 1 '.' (periods), then a space, then an upper case letter between A-Z then 0 or more word characters
USE GROUPS use parentheses to specify characters to search for different patters (a|b) or (1|2) EXAMPLE 1:
` pattern = re.compile(r'M(r
EXAMPLE SEARCH FOR EMAIL EXAMPLE 1:
` pattern = re.compile(r'[a-zA-Z0-9.-]+@[a-zA-Z-]+.(com
EXAMPLE SEARCH FOR URL use parentheses to create groups within the url to pull out of later () *note: Parentheses enlarged in example for clarity of usage. EXAMPLE 1:
pattern = re.compile(r'https?://(www.)?(\w+)(\.\w+)')
RETURN NOTE:
only matches 'http' then 0 or 1 's', then '://', then 0 or 1 'www.' then 1 or more \word characters then a '.' followed by one or more word characters.
GROUP METHOD, PULL OUT SPECIFIC GROUPS FROM EXPRESIONS use parentheses to create groups within the url to pull out of later () *note: Parentheses enlarged in example for clarity of usage. EXAMPLE: GROUP 0
pattern = re.compile(r'https?://(www.)?(\w+)(\.\w+)')
matches = pattern.finditer(urls) for match in matches: print(match.group(0))
RETURN NOTE: group(0) is the entire expression So it would be: https://www.google.com http://coreyms.com https://youtube.com https://www.nasa.gov


EXAMPLE: GROUP 1
pattern = re.compile(r'https?://(www.)?(\w+)(\.\w+)')
matches = pattern.finditer(urls) for match in matches: print(match.group(1))

RETURN NOTE:
group(1) is the optional group noted in the expression www. None None www.


EXAMPLE: GROUP 2
pattern = re.compile(r'https?://(www.)?(\w+)(\.\w+)')
matches = pattern.finditer(urls) for match in matches: print(match.group(2))
RETURN NOTE: group(2) is the second group noted in the expression
google coreyms youtube nasa

EXAMPLE: GROUP 3

pattern = re.compile(r'https?://(www.)?(\w+)(\.\w+)')
matches = pattern.finditer(urls)
for match in matches:
print(match.group(3))

RETURN NOTE:
group(3) is the thrid group noted in the expression .com .com .com .gov
SUB method REFERENCING GROUPS use sub method to replace items from patterns. *note: Parentheses enlarged in example for clarity of usage. EXAMPLE: SUB URLS
pattern = re.compile(r'https?://(www.)?(\w+)(\.\w+)')
subbed_urls = pattern.sub(r'\2\3', urls)
print(subbed_urls)

RETURN NOTE:

subbed urls:
google.com
coreyms.com
youtube.com
nasa.gov
.FINDALL METHOD EXAMPLE 1:
`pattern = re.compile(r'M(r
.MATCH METHOD EXAMPLE 1: pattern = re.compile(r'Start') matches = pattern.match(sentence) RETURN NOTE: will only return matches at BEGINNING OF STRING.
.SEARCH METHOD EXAMPLE 1: pattern = re.compile(r'a') matches = pattern.search(sentence) RETURN NOTE: will only return first match that it finds.
USING FLAGS EXAMPLE 1: pattern = re.compile(r'start', re.IGNORECASE) matches = pattern.search(sentence) RETURN NOTE: will ignore the case of any characters in string and return first match. EXAMPLE 2: pattern = re.compile(r'start', re.I) matches = pattern.search(sentence) RETURN NOTE: will ignore the case of any characters in string and return first match.
Use .start() and .end() to extract text ``import re<br /><br />##string to search<br />SEARCH_STRING = {PLACE STRING HERE}`


##start and finish extraction
`start_regex = re.compile(r'STARTING_STRING')`
`start = [i for i in start_regex.finditer(SEARCH_STRING)][0].end()`
`finish_regex = re.compile(r'&scope')`
`finish = [i for i in finish_regex.finditer(SEARCH_STRING)][0].start()`

##result
`RESULT = SEARCH_STRING[start:finish]`
