通过忽略索引来连接DataFrame：
为了通过忽略索引来连接数据帧，我们忽略没有有意义含义的索引，您可能希望附加它们并忽略它们
可能具有重叠索引的事实。为了做到这一点，我们 ignore_index用作参数。

# importing pandas module
import pandas as pd

# Define a dictionary containing employee data
data1 = {'Name':['Jai', 'Princi', 'Gaurav', 'Anuj'],
'Age':[27, 24, 22, 32],
'Address':['Nagpur', 'Kanpur', 'Allahabad', 'Kannuaj'],
'Qualification':['Msc', 'MA', 'MCA', 'Phd'],
'Mobile No': [97, 91, 58, 76]}

# Define a dictionary containing employee data
data2 = {'Name':['Gaurav', 'Anuj', 'Dhiraj', 'Hitesh'],
'Age':[22, 32, 12, 52],
'Address':['Allahabad', 'Kannuaj', 'Allahabad', 'Kannuaj'],
'Qualification':['MCA', 'Phd', 'Bcom', 'B.hons'],
'Salary':[1000, 2000, 3000, 4000]}

# Convert the dictionary into DataFrame 
df = pd.DataFrame(data1,index=[0, 1, 2, 3])

# Convert the dictionary into DataFrame 
df1 = pd.DataFrame(data2, index=[2, 3, 6, 7])


print(df, "\n\n", df1)
