To remove commas from columns of a pandas dataframe, you can use the str.replace
method along with the df.apply
function to iterate over each column and remove the commas. Here's an example code snippet that demonstrates this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
import pandas as pd # Create a sample dataframe data = {'A': ['1,000', '2,000', '3,000'], 'B': ['4,000', '5,000', '6,000']} df = pd.DataFrame(data) # Function to remove commas from a column def remove_commas(column): return column.str.replace(',', '') # Apply the function to each column in the dataframe df = df.apply(remove_commas) # Print the updated dataframe without commas print(df) |
In this code snippet, we define a function remove_commas
that removes commas from a column using the str.replace
method. We then apply this function to each column in the dataframe using the df.apply
function, which returns a new dataframe with the commas removed. Finally, we print the updated dataframe without commas.
How do I replace commas with spaces in columns of a pandas dataframe?
You can use the replace()
method in pandas to replace commas with spaces in columns of a dataframe. Here's an example on how to do it:
1 2 3 4 5 6 7 8 9 10 11 |
import pandas as pd # Create a sample dataframe df = pd.DataFrame({'A': ['1,234', '2,345', '3,456'], 'B': ['4,567', '5,678', '6,789']}) # Replace commas with spaces in columns 'A' and 'B' df['A'] = df['A'].str.replace(',', ' ') df['B'] = df['B'].str.replace(',', ' ') print(df) |
This code will replace commas with spaces in columns 'A' and 'B' of the dataframe df
. You can modify the code to include more columns or use a loop to iterate through multiple columns if needed.
What is the correct syntax for removing commas from columns of a pandas dataframe?
To remove commas from columns of a pandas dataframe, you can use the following syntax:
1
|
df['column_name'] = df['column_name'].str.replace(',', '')
|
This will replace any commas in the specified column with an empty string, effectively removing them from the data.
How to strip commas from columns in a pandas dataframe?
You can remove commas from columns in a pandas dataframe by using the str.replace()
method along with a lambda function. Here's an example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
import pandas as pd # Create a sample dataframe data = {'A': ['1,000', '2,000', '3,000'], 'B': ['4,000', '5,000', '6,000']} df = pd.DataFrame(data) # Remove commas from column 'A' df['A'] = df['A'].apply(lambda x: x.replace(',', '')) # Remove commas from column 'B' df['B'] = df['B'].apply(lambda x: x.replace(',', '') print(df) |
This will output:
1 2 3 4 |
A B 0 1000 4000 1 2000 5000 2 3000 6000 |
In this example, we used apply()
along with a lambda function to remove commas from each value in columns 'A' and 'B of the dataframe.
