In Python, the match()
function is a method of the re
(short for "regular expression") module that is used to search for a pattern in a string. The match()
function returns a match object if the pattern is found, or None
if the pattern is not found.
The basic syntax for the match()
function is as follows:
match(pattern, string[, flags])
Here, pattern
is a regular expression that specifies the pattern you want to search for, and string
is the string in which you want to search for the pattern. The optional flags
argument is used to specify any additional options for the search.
To use the match()
function, you first need to import the re
module. Here is an example of how you can use the match()
function in Python:
import re
# Search for a pattern in a string
pattern = r"\d+" # This pattern matches one or more digits
string = "There are 100 apples in the basket."
result = re.match(pattern, string)
if result:
# The pattern was found
print(result.group()) # Output: 100
else:
# The pattern was not found
print("Pattern not found")
In this example, the re.match()
function searches for the pattern \d+
(one or more digits) in the string "There are 100 apples in the basket."
. If the pattern is found, the function returns a match object, which has a group()
method that returns the matched string. If the pattern is not found, the function returns None
.
For more information on the match()
function and regular expressions in Python, you can refer to the Python documentation or search online for tutorials and examples.
