python - Comparing the content a List of pandas DataFrames -

i have list contains 3 pandas dataframes. dataframes have exact column names , have same length. compare entries of specific column in each dataframe. assuming list has:

list=[df1,df2,df3]. 

and each dataframe has following structure. df1 has structure

column1    column2   column3   4          3          4   4          5          7   7          6          6   8          6          4 

df2 has structure

column1    column2   column3   4          3          4   7          5          7   7          6          5   8          6          4 

df3 has structure

column1    column2   column3   4          3          5   4          1          7   7          6          6   8          6          4 

i compare content of df1 column1 , column2(for each row) contain df2 (column1 , column2) , df3 (column1 , column2)

i wrote thought this:

for in range(len(list)):# iterate through list     j in range(len(list[0].index.values)):# iterate through the whole dataframe     #i like: if df1[column1][row1]=df2[column1][row1] ....     # dont know how iterate through dataframes simulatanously compare content of of column 1 , column 2(for each row k) of df1 content of column 1 , column 2 of df2 , column 1 , column 2 of df3. 

i stuck there
