вернуть таблицу выбранных функций панд

# Below are quick example

# By using df[] Notation to select multiple columns
df2 = df[["Courses","Fee","Duration"]] 

# Using loc[] to take column slices
df2 = df.loc[:, ["Courses","Fee","Duration"]] # Selecte multiple columns
df2 = df.loc[:, ["Courses","Fee","Discount"]] # Select Random columns
df2 = df.loc[:,'Fee':'Discount'] # Select columns between two columns
df2 = df.loc[:,'Duration':]  # Select columns by range
df2 = df.loc[:,:'Duration']  # Select columns by range
df2 = df.loc[:,::2]          # Select every alternate column

# Using iloc[] to select column by Index
df2 = df.iloc[:,[1,3,4]] # Select columns by Index
df2 = df.iloc[:,1:4] # Select between indexes 1 and 4 (2,3,4)
df2 = df.iloc[:,2:] # Select From 3rd to end
df2 = df.iloc[:,:2] # Select First Two Columns

#Using get()
df2 = df.get(['Courses','Fee'])
