Python - Data Analytics - Real World Hands-on Projects

In this course, we have uploaded 8 Data Analytics Projects, solved with Python.

These projects can used if you are looking for a starting level job as a Data Analyst.

If you are a student, you can use these projects to submit in college/institute.

The source codes and datasets files are available to download.

All the projects are created with a very easy explanation.

We have mainly used the popular Python Pandas Library, along with Matplotlib to solve these projects.

The projects are :

• Project 1 - Weather Data Analysis

• Project 2 - Cars Data Analysis

• Project 3 - Police Data Analysis

• Project 4 - Covid Data Analysis

• Project 5 - London Housing Data Analysis

• Project 6 - Census Data Analysis

• Project 7 - Udemy Data Analysis

• Project 8 - Netflix Data Analysis

  
  

Some basic examples of commands used in these projects are :

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

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

* index - This attribute provides the index of the dataframe

* columns - It shows the name of each column

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

* 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.

* 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.

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

* info() - Provides basic information about the dataframe.* size - To show No. of total values(elements) in the dataset.

* duplicated( ) - To check row wise and detect the Duplicate rows.

* 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.

* to_datetime( ) - Converts the data-type of Date-Time Column into datetime[ns] datatype.

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

* groupby( ) - Groupby is used to split the data into groups based on some criteria.

* 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.

* mean( ) - It shows the mean value of the series.
