It can be applied to a single column only. • df[df.Col_1 = = ‘Element1’] - Filtering – We are accessing all records with Element1 only of Col_1. • df.sort_values(‘Col_name' , ascending=False ) - To sort the dataframe wrt any column values in descending order. • df[ (df.Col1 = = ‘Element1’) (df.Col2 == ‘Element2’) ] - Multilevel filtering - And Filter – Filtering the data with two more items. • str.contains('Value_to_match’) - To find the records that contains a particular string. • dtypes - To show datatypes of each column. • pd.to_datetime(df.Date_Time_Col) - To convert the data-type of Date-Time Column into datetime[ns] datatype. • dt.year - Creating a new column with only year values. • df.groupby(‘Col_1’)['Col_2'].max() - Using groupby with two different columns. • ....................................................................... • Q. 1) What are all different subjects for which Udemy is offering courses ? • Q. 2) Which subject has the maximum number of courses. • Q. 3) Show all the courses which are Free of Cost. • Q. 4) Show all the courses which are Paid. • Q. 5) Which are Top Selling Courses ? • Q. 6) Which are Least Selling Courses ? • Q. 7) Show all courses of Graphic Design where the price is below 100 ? • Q. 8) List out all the courses that are related to 'Python'. • Q. 9) What are courses that were published in the year 2015 ? • Q. 10) What is the Max.
