Saving data in vertical column format in Python-CodePudding

I am trying to save the list Mean1 in vertical column format. I present the current and expected outputs.

Mean1= [25.482954545454543,
 9.914772727272727,
 5.369318181818182,
 4.545454545454545,
 4.318181818181818,
 4.176136363636363,
 4.119318181818182,
 4.090909090909091,
 4.0625,
 4.0625]

with open('Mean.csv', 'w ') as f: 
    
        f.write(f"Mean1 = {str(Mean1)}\n")

The current output is

The expected output is

Try this :

import csv

Mean1= [25.482954545454543,
 9.914772727272727,
 5.369318181818182,
 4.545454545454545,
 4.318181818181818,
 4.176136363636363,
 4.119318181818182,
 4.090909090909091,
 4.0625,
 4.0625]

Mean1 = [[e] for e in Mean1]

with open(r'path_to_your_outputCsv.csv', 'w', newline="\n") as f:
    wr = csv.writer(f)
    wr.writerow(['Mean1'])
    wr.writerows(Mean1)

Or, if you're fine with pandas, you can store the elements of a list (each in one separated row) in a .csv by using pandas.DataFrame and pandas.DataFrame.to_csv combined.

#pip install pandas
import pandas as pd

Mean1= [25.482954545454543,
 9.914772727272727,
 5.369318181818182,
 4.545454545454545,
 4.318181818181818,
 4.176136363636363,
 4.119318181818182,
 4.090909090909091,
 4.0625,
 4.0625]

pd.DataFrame(Mean1, columns=['Mean1']).to_csv(r'path_to_your_outputCsv.csv', index=False)
