  1. Introduction to Pandas
  2. Series
  3. DataFrames
  4. Missing Data
  5. GroupBy
  6. Merging,Joining,and Concatenating
  7. Operations
  8. Data Input and Output
SOME EXAMPLE ON PANDAS:
3.1 example:
Let us now create an indexed DataFrame using array.



import pandas as pd



data = {'Name':['sachin', 'pagar', 'sunil', 'Rahul'],'Age':[28,34,29,42]}


df = pd.DataFrame(data, index=['rank1','rank2','rank3','rank4'])


print df

Its output is as follows −


Age Name




rank1 28 sachin


rank2 34 pagar


rank4 42 Rahul




rank3 29 Sunil





3.2 example:




import pandas as pd



data = {'Name':['sachin', 'ram', 'sham', 'gokul'],'Age':[28,34,29,42]}


df = pd.DataFrame(data)


print df

Its output is as follows −


Age Name




0 28 sachin


1 34 ram


3 42 gokul




2 29 Sham


3.3 Example:




import pandas as pd



data = [['Alisha',10],['Ashwini',12],['Apeksha',13]]


df = pd.DataFrame(data,columns=['Name','Age'],dtype=float)


print df

Its output is as follows −


Name Age




0 Alisha 10.0


1 Ashwini 12.0


2 Apeksha 13.0


Some FAQ on Pandas

1. Why Pandas are used in Python?
In simple way Pandas is a Library in Computer Programming. It is written for the support programming in  Python Programming Language . With the help of python library we do the programming work for data analysis and manipulation.In the simpler word, Pandas help us  putting the data in a tabular form.

2. What is NumPy and pandas in Python?
What is Numpy? Similar to pandasNumpy is one of the most widely used python library in data science. It provide high-performance to us, easy to use structure and data analysis tool in python. Unlike Pandas library which provides object for the multi-dimensional array, Pandas provides in-memory table objects called Dataframe object.

3. What is difference between Numpy and pandas?
Key DifferencesPandas library which provides object for the multi-dimensional array, Pandas provides in-memory table objects called Dataframe object whereas library which provides object for the multi-dimensional array, Pandas provides in-memory table objects called Dataframe object.

4. Is Numpy faster than pandas?

From the different observation on function function, the NumPy array can be significantly performed the faster  operations than Pandas series. NumPy array can be used in place of Pandas serie if the more functionality offered by Pandas series is not critical.


See the Package overview for more detail about what’s in the librarys.
