**To change a value in a dataframe in Python, you can use the loc[] method to access a specific cell by its row and column labels, and then assign a new value to it.**<\/p>\n

For example, suppose you have a dataframe called df and you want to change the value in the cell at row 3 and column ‘A’ to 10. You can do this by using the following code:<\/p>\n

“`python
\nimport pandas as pd<\/p>\n

# Create a sample dataframe
\ndf = pd.DataFrame({‘A’: [1, 2, 3, 4], ‘B’: [5, 6, 7, 8]})<\/p>\n

# Change the value in the cell at row 3 and column ‘A’ to 10
\ndf.loc[3, ‘A’] = 10
\n“`<\/p>\n

This will update the dataframe df with the new value 10 in the specified cell.<\/p>\n
