To drop columns that have missing values in Python using pandas, you can follow these steps:
main.py20 chars2 lines
main.py37 chars2 lines
dropna
method:main.py32 chars2 lines
This will drop all the columns that have at least one missing value.
thresh
parameter of the dropna
method to the number of non-missing values required:main.py52 chars2 lines
This will drop the columns that have missing values in more than 10% of the rows.
main.py31 chars2 lines
Note that the above steps will drop the columns that have missing values completely, which may result in the loss of valuable information. Make sure to consider the implications of dropping those columns before doing so. Additionally, if you want to drop the rows instead of the columns, you can change axis=1
to axis=0
in the dropna
method.
Remember to save the modified DataFrame if you wish to persist the changes.
