What are some effective data cleaning methods in Pandas?
Some effective data cleaning methods in Pandas include handling missing values, removing duplicates, and converting data types.
How can I handle missing values in my DataFrame?
You can handle missing values using methods like fillna()
, dropna()
, or by using interpolation.
What does the drop_duplicates()
function do?
The drop_duplicates()
function removes duplicate rows from your DataFrame, keeping the first occurrence by default.
Can you show me an example of using fillna()
?
Sure! You can use df.fillna(value)
to replace NaN values with a specified value, like df.fillna(0)
to replace NaNs with 0.
