To rename pandas column names by splitting with space, you can use the str.split() method along with the .str accessor to split the column names based on the space character. After splitting the column names, you can assign the new names to the DataFrame's columns attribute. Here's an example:

import pandas as pd

Create a sample DataFrame

data = {'First Name': [1, 2, 3], 'Last Name': [4, 5, 6]} df = pd.DataFrame(data)

Split column names by space

new_columns = df.columns.str.split().str.join('_')

Rename the columns

df.columns = new_columns

print(df)

This will rename the column names 'First Name' and 'Last Name' to 'First_Name' and 'Last_Name' respectively.

How can I rename column names in pandas by splitting them with space in Python?

You can rename column names in a pandas DataFrame by using the rename() function along with a lambda function that splits the column names with space. Here's an example:

import pandas as pd

Sample DataFrame

df = pd.DataFrame({'First Name': ['Alice', 'Bob', 'Charlie'], 'Last Name': ['Smith', 'Jones', 'Brown']})

Rename column names by splitting with space

df.rename(columns=lambda x: x.split()[0] + '_' + x.split()[1], inplace=True)

print(df)

This will rename the column names 'First Name' and 'Last Name' to 'First_Name' and 'Last_Name', respectively. You can modify the lambda function to suit your specific naming convention.

How do I rename pandas column names by splitting with space in Python?

You can rename pandas column names by splitting them with a space using the str.split() method and then assigning the new column names to the columns attribute of the DataFrame. Here's an example:

import pandas as pd

Sample DataFrame

data = {'First Name': [1, 2, 3], 'Last Name': [4, 5, 6]} df = pd.DataFrame(data)

Split column names with space and rename columns

df.columns = df.columns.str.split().str.join('_')

print(df)

This will output:

First_Name Last_Name 0 1 4 1 2 5 2 3 6

In this example, we split the column names with a space and then joined the split parts with an underscore to create the new column names. Finally, we assigned these new column names to the columns attribute of the DataFrame.

How to rename column names in pandas by splitting by space?

You can rename column names in pandas by splitting them using the str.split() method and then joining them back together with a custom separator. Here's an example:

import pandas as pd

Sample DataFrame

data = { 'First Name': [ 'John', 'Jane', 'James'], 'Last Name': ['Doe', 'Smith', 'Brown'], 'Age': [25, 30, 35] }

df = pd.DataFrame(data)

Split and join column names

df.columns = df.columns.str.split().str.join('_')

print(df)

This code will split column names by space and join them back together with an underscore separator, resulting in the following DataFrame:

First_Name Last_Name Age 0 John Doe 25 1 Jane Smith 30 2 James Brown 35

What is the code to change column names in pandas by splitting with space?

You can use the rename method in pandas to change column names by splitting with space. Here is an example code to achieve this:

import pandas as pd

Example dataframe

data = {'First Name': [1, 2, 3], 'Last Name': [4, 5, 6]} df = pd.DataFrame(data)

Split column names by space and rename columns

df.columns = df.columns.str.split().str.join('_')

Display the updated dataframe

print(df)

This code will split the column names by space and join them with an underscore, resulting in column names like First_Name and Last_Name.

What is the result of renaming pandas column names by splitting with space?

The result of renaming pandas column names by splitting with space would be that each column name is split into multiple parts, with each part becoming a separate column name. For example, if the original column name is "First Name", splitting with space would result in two new column names "First" and "Name".
