To delete a row or n rows from a pandas dataframe you can use following command
DataFrame.drop(labels=None, axis=0, index=None, columns=None, level=None, inplace=False, errors='raise')
Let's assume you have a dataframe with 100 employees data with employee id's ranging from 1 to 100. If you want to drop all employees from dataframe with employee id between 5 and 10. Then you can use following command to do this.
df.drop(df.loc[((df.emp_id >= 5) & (df.emp_id <= 10))].index, inplace=True)
If you want to drop all employees with employee id greater than 90. Then you can modify above as following.
df.drop(df.loc[df.emp_id > 90].index, inplace=True)
For more such tips stay tuned.
