re.findall():

• It find all sub strings where the RE matches, and return them as a list. This function is used to catch all the matching patterns in the strings.

Note Worthy: re.match() + re.search() = re.findall()

Syntax:

  re.findall(pattern, string)

Source Code:

  import re

  variable = re.findall(r"Google", "Google Bird learn around Google and gives the best contents to the viewrs")

  print variable

Output:

   ['Google', 'Google']

re.sub():

• This is used to search a pattern in the string an replace with the new sub string.

Syntax:

re.sub(pattern, replacement_string, string )

Source Code:

  import re

  variable = re.sub(r"viewers","Learners to learn easily",  "Google Bird learn around Google and gives the best contents to the viewers")

  print variable
