Here is the required code for these two problems. Let me know if you have any doubts or if you need anything to change. If you are satisfied with the solution, please rate the answer. If not, PLEASE let me know before you rate, I’ll help you fix whatever issues. Thanks

# assuming pandas is imported as: import pandas as pd
# and example_df & example2_df are two dataframes.

# code that merges example_df and example2_df by x column
merged_df = pd.merge(left=example_df, right=example2_df, left_on='x', right_on='x')

# code that writes "merged_df" to a CSV file named "merged.csv"
merged_df.to_csv('merged.csv')
