Python - Regular expression to get only the first word from each line

Python - Regular expression to get only the first word from each line

To get only the first word from each line using regular expressions in Python, you can use the following pattern:

import re pattern = r'^\w+'

Explanation of the pattern:

  • ^: Asserts the start of the line.
  • \w+: Matches one or more word characters (alphanumeric characters and underscores).

This pattern matches the first word of each line in a multiline string.

Here's an example of how to use this pattern in Python:

import re pattern = r'^\w+' text = """ The quick brown fox Jumps over the lazy dog Python is awesome """ matches = re.findall(pattern, text, re.MULTILINE) print(matches)

Output:

['The', 'Jumps', 'Python']

Examples

  1. "Python regex to get first word from each line"

    Description: Users are searching for a regular expression in Python to extract only the first word from each line of text data.

    Code Implementation:

    import re text = """ Hello world Python is awesome Regular expressions are powerful """ first_words = re.findall(r'^\w+', text, re.MULTILINE) print(first_words) # Output: ['Hello', 'Python', 'Regular']

  2. "Python regex to extract initial word from each line"

    Description: This query indicates users want a regular expression in Python to capture the initial word from each line of text.

    Code Implementation:

    import re text = """ Alpha is the first letter Beta comes after Alpha Gamma is the third letter """ initial_words = re.findall(r'^\w+', text, re.MULTILINE) print(initial_words) # Output: ['Alpha', 'Beta', 'Gamma']

  3. "Python regex to get start word from each line"

    Description: Users are interested in a regular expression in Python to identify and extract the starting word from each line of text.

    Code Implementation:

    import re text = """ Start of the day Morning brings sunshine """ start_words = re.findall(r'^\w+', text, re.MULTILINE) print(start_words) # Output: ['Start', 'Morning']

  4. "Python regex to fetch leading word from each line"

    Description: This query suggests users want a Python regular expression to fetch the leading word from every line of text.

    Code Implementation:

    import re text = """ Leading by example Leadership qualities matter """ leading_words = re.findall(r'^\w+', text, re.MULTILINE) print(leading_words) # Output: ['Leading', 'Leadership']

  5. "Python regex to capture first token from each line"

    Description: Users are searching for a regular expression in Python to capture the first token (word) from each line of text.

    Code Implementation:

    import re text = """ Tokenizing the text Extracting meaningful information """ first_tokens = re.findall(r'^\w+', text, re.MULTILINE) print(first_tokens) # Output: ['Tokenizing', 'Extracting']

  6. "Python regex to get initial word from multiline string"

    Description: This query indicates users want a Python regular expression to retrieve the initial word from each line in a multiline string.

    Code Implementation:

    import re text = """First line Second line Third line""" initial_words = re.findall(r'^\w+', text, re.MULTILINE) print(initial_words) # Output: ['First', 'Second', 'Third']

  7. "Python regex to extract only first word per line"

    Description: Users want a regular expression in Python specifically designed to extract only the first word from each line in a text block.

    Code Implementation:

    import re text = """ Extracting the initial word Getting the start of each line """ first_words = re.findall(r'^\w+', text, re.MULTILINE) print(first_words) # Output: ['Extracting', 'Getting']

  8. "Python regex to get beginning word from each line"

    Description: This query suggests users want a Python regular expression to capture the word at the beginning of every line in a text block.

    Code Implementation:

    import re text = """ Beginning of the story Start of a new chapter """ beginning_words = re.findall(r'^\w+', text, re.MULTILINE) print(beginning_words) # Output: ['Beginning', 'Start']

  9. "Python regex to match only first word on each line"

    Description: Users are looking for a regular expression in Python that exclusively matches the first word on every line in a text document.

    Code Implementation:

    import re text = """ Match only initial word Find the starting word """ first_words = re.findall(r'^\w+', text, re.MULTILINE) print(first_words) # Output: ['Match', 'Find']

  10. "Python regex to capture first word from multiple lines"

    Description: This query suggests users want a Python regular expression to capture the first word from multiple lines of text.

    Code Implementation:

    import re text = """ Capturing initial word Grabbing the leading token """ first_words = re.findall(r'^\w+', text, re.MULTILINE) print(first_words) # Output: ['Capturing', 'Grabbing']
