Concatenating two DataFrames, and then finding the Maximum value
from pandas import DataFrame
Data1 = {'Set1': [55,22,11,77,33]}
df1 = DataFrame(Data1, columns= ['Set1'])
Data2 = {'Set2': [23,45,21,73,48]}
df2 = DataFrame(Data2, columns= ['Set2'])
Concatenated = df1['Set1'].map(str) + df2['Set2'].map(str)
df_combined = DataFrame(Concatenated, columns=['Combined Values'])
max1 = df_combined['Combined Values'].max()
print (max1)
