Pandas - Split a column of values delimited by a space into separate columns for each value in python

You can split a column of values delimited by a space into separate columns for each value using the str.split() function in pandas. Here's how you can do it:

import pandas as pd # Sample DataFrame data = {'column': ['value1 value2 value3', 'value4 value5 value6']} df = pd.DataFrame(data) # Split the values in the column and expand them into separate columns df[['col1', 'col2', 'col3']] = df['column'].str.split(expand=True) # Drop the original column if needed # df.drop(columns=['column'], inplace=True) print(df)

Output:

 column col1 col2 col3 0 value1 value2 value3 value1 value2 value3 value1 value2 value3 1 value4 value5 value6 value4 value5 value6 value4 value5 value6

In this code:

  • We first create a sample DataFrame with a column named 'column' containing strings with values delimited by a space.
  • We then use the str.split() function on the 'column' to split the values based on the space delimiter. Setting expand=True expands the result into separate columns.
  • Finally, we assign the result of the split operation to new columns 'col1', 'col2', and 'col3'.

You can adjust the number of new columns based on the maximum number of values you expect in the original column. If the number of values varies, you may need to handle missing or additional columns accordingly.

Examples

  1. "Python pandas split column by space"

    • Description: This query is about splitting a column in a Pandas DataFrame where values are separated by spaces.
    import pandas as pd # Sample DataFrame df = pd.DataFrame({'col': ['apple orange', 'banana cherry']}) # Splitting column 'col' into separate columns df[['fruit1', 'fruit2']] = df['col'].str.split(' ', expand=True)

  2. "Pandas split string into multiple columns"

    • Description: This query aims to divide a string column into multiple columns based on a delimiter using Pandas.
    import pandas as pd # Sample DataFrame df = pd.DataFrame({'col': ['red green blue', 'yellow black white']}) # Splitting column 'col' into separate columns df[['color1', 'color2', 'color3']] = df['col'].str.split(' ', expand=True)

  3. "Split column into multiple columns pandas"

    • Description: This query seeks to split a single column into multiple columns in a Pandas DataFrame.
    import pandas as pd # Sample DataFrame df = pd.DataFrame({'col': ['A B', 'C D E']}) # Splitting column 'col' into separate columns df[['letter1', 'letter2', 'letter3']] = df['col'].str.split(' ', expand=True)

  4. "Python pandas separate column by space"

    • Description: This query involves separating a column in a Pandas DataFrame where values are separated by spaces.
    import pandas as pd # Sample DataFrame df = pd.DataFrame({'col': ['1 2', '3 4 5']}) # Splitting column 'col' into separate columns df[['num1', 'num2', 'num3']] = df['col'].str.split(' ', expand=True)

  5. "Pandas split column by delimiter"

    • Description: This query is about splitting a column using a specified delimiter in a Pandas DataFrame.
    import pandas as pd # Sample DataFrame df = pd.DataFrame({'col': ['x-y', 'a-b-c']}) # Splitting column 'col' into separate columns df[['char1', 'char2', 'char3']] = df['col'].str.split('-', expand=True)

  6. "Pandas split string into multiple columns by space"

    • Description: This query intends to split a string column into multiple columns based on spaces using Pandas.
    import pandas as pd # Sample DataFrame df = pd.DataFrame({'col': ['one two three', 'four five']}) # Splitting column 'col' into separate columns df[['word1', 'word2', 'word3']] = df['col'].str.split(' ', expand=True)

  8. "Pandas separate column values by space"

    • Description: This query looks for a way to separate values within a column by spaces using Pandas.
    import pandas as pd # Sample DataFrame df = pd.DataFrame({'col': ['apples oranges', 'bananas']}) # Splitting column 'col' into separate columns df[['fruit1', 'fruit2']] = df['col'].str.split(' ', expand=True)
