Pandas – DataFrame object – Online Programming Tutorials

Python – Data Frames: A Data frame is a two-dimensional data structure, i.e., data is aligned in a tabular fashion in rows and columns.

import pandas as pd
frame = pd.DataFrame()
print(frame)

We can store information in rows and columns using sub lists :

import pandas as pd
data = [[10,'abc'],[20,'xyz'],[30,'lmn']]
frame = pd.DataFrame(data,columns=['ID','Name'])
print(frame)

We can specify the data type :

import pandas as pd
data = [['hareen',21],['annie',19],['hari',23]]
frame = pd.DataFrame(data,columns=['Name','Age'],dtype=float)
print(frame)

Create a DataFrame from Dict of ndarrays / Lists :

import pandas as pd
data = {'Emp':['Syam','harini','ricky','raksha'],'Age':[21,19,23,21]}
frame = pd.DataFrame(data)
print(frame)
