* std()  - To check the standard deviation of any numerical column.

* var()  - To check the variance of any numerical column.

* mean()  - To check the mean of any numerical column.

* agg() - Using agg() with groupby().

* head() - It shows the first N rows in the data (by default, N=5).

* columns - To show all the column names of the dataframe.

* unique() - In a column, it shows all the unique values. It can be applied on a single column only, not on the whole dataframe.

* nunique() - It shows the total no. of unique values in each column. It can be applied on a single column as well as on the whole dataframe.

* describe() - To show some summary about the columns.

* astype() - To change the datatype of any column.

* value_counts - In a column, it shows all the unique values with their count. It can be applied on a single column only.

* plot(kind='bar') - To draw the bar graph.

* type() - To the type of any variable.

* plt.figure(figsize = ()) - To set the size of any figure.

* plt.title(), plt.xlabel(), plt.ylabel() - To set the Title, x-axis label, y-axis label.

* sort_values(ascending = False) - To sort the values in descending order.

* dt.month - To create a new column showing Month only.

* shape - It shows the total no. of rows and no. of columns of the dataframe

* index - This attribute provides the index of the dataframe

* dtypes - It shows the data-type of each column

* count - It shows the total no. of non-null values in each column. It can be applied on a single column as well as on the whole dataframe.

* isnull( ) - To show where Null value is present.

* dropna( ) - It drops the rows that contains all missing values.

* isin( ) - To show all records including particular elements.

* str.contains( ) - To get all records that contains a given string.

* str.split( ) - It splits a column's string into different columns.

* dt.year.value_counts( ) - It counts the occurrence of all individual years in Time column.

* sns.countplot(df['Col_name']) - To show the count of all unique values of any column in the form of bar graph.

* max( ), min( ) - It shows the maximum/minimum value of the series
