Hi all,

I have a csv file from which I correctly take a string in a list (list1). In the csv file the element is like:

row
row2
row3
row4

When i print the list1 the output is like:

[row \n row2 \n row3 \n row4]

What should i do to print like

row
row2
row3
row4

??

Thanks

The list you have shown is not a valid list, if your list actually looks like this ['row \n', 'row2 \n', 'row3 \n', 'row4'] the following will print each item on a separate line.

list1 = ['row \n', 'row2 \n', 'row3 \n', 'row4']
for item in list1:
    print(item.strip())

Output:
row
row2
row3
row4

I explain you what i have done.

Made a string like:

str = text + '\n' + text + '\n' + text + '\n' + text

I saved the str in .csv file.

When i extract it from .csv file and insert it in a list and print it i got

[row1\n row2\n row3\n row4]

full list is: ["row1\n row2\n row3\n row4", "row\n row\n row\n row" ]

instead of:

row1
row2
row3
row4

why?

If the list looks like this

list1 = ["row1 \n row2 \n row3 \n row4", "row \n row \n row \n row" ]

and the list is printed it will be a representation of the list.

print(list1)

Output:
['row1 \n row2 \n row3 \n row4', 'row \n row \n row \n row']

if an item from the list is printed it will be a representation of the item.

print(list1[0])

Output:
row1
 row2
 row3
 row4

Only actual code can be debugged, not a vague description of what the actual code does.

with open(file, 'r', newline='') as csvfile: 
            
    reader = csv.reader(csvfile, delimiter=';')

    for row in reader:

        tabella_risultati_vecchi.append(row)


for row in tabella_risultati_vecchi:

    print(row)

RESULT:

Written with this code:

with open(file,'w', newline='') as csvfile: 

    writer = csv.writer(csvfile, delimiter=';')

    for row in tabella_risultati:
        
        if row.find(giocatore_seguire) != -1:
            
            writer.writerow([row])

I tryed to use print(tabella_risultati_vecchi[0]) but it's the same.

Resolved !

Thanks for advice
