Pandas Replace | pd.DataFrame.replace()

Want to replace values in your DataFrame with something else? No problem. That is where pandas replace comes in.

Can a data scientist provide guidance?
How would I replace the characters "/\" with a string like "E:\IMAGES\ITEMS\product\"?

I tried this and it doesn't work, and I'm certain the "Image" column name is correct:
df['Image'] = df['Image'].replace("/\\",

Your videos are very helpful and easy to understand! Is there a way we can reference a csv file in the replace function? So instead of hard coding the values I'd like to replace, can I reference a file that contains the values to be replaced? Thank you!!

I'm quite new to python.

I have a CSV file that has columns mixed with time in text format '0:00:00' and nulls represented in '-'. When I bulk insert to SQL Server, the columns are recognized as varchar(MAX). I want them in float so I can sum them later on.

I tried this but nothing changed. Is there a commit or append line that I need to do?

Great tutorial mate. Is there a way I can replace a range of cells (e.g rows from index position 2 through to index position 10) in a column of a dataframe (not sure how I should select them) with the values from a list. Is this possible? I hope the way I've worded this makes sense. Let me know if it's not clear. Any help very much appreciated.

Hello sir. I have a question. How to use cell data for modifying/.replace in text file . E. g. I have a excel file. In which cell A1=20677555. And want to use this value/data. To .replace with a different number. Which is available in text file.
Data.replace(cell A1 data', 'text file available data').

'Max Speed': [380., 370., 24., 26.]})

'No Falcon'}, value=None)

2:42 On my side, it only works if you remove value=None, if do not remove it, the dataframe does not change.
