merge dataframes with same columns names but different types code example

Example 1: pandas merge two columns from different dataframes

#suppose you have two dataframes df1 and df2, and 
#you need to merge them along the column id
df_merge_col = pd.merge(df1, df2, on='id')

Example 2: merge two dataframes with common columns

dfinal = df1.merge(df2, how='inner', left_on='movie_title', right_on='movie_name')
