I'm using append and its adding \n at the end of each element

Question

The Code:

import csv

symbols = []
with open("I:/my500.csv") as f:
    for row in f:
        symbols.append(row)

The output:

['SPY\n', 'WMT\n', 'GLD\n', 'IBM\n']

Answer 1

That's because when you iterate through a file, the lines contain a newline. To solve this, you can .rstrip() them.

symbols = []
with open("I:/my500.csv") as f:
    for row in f:
        symbols.append(row.rstrip('\n'))

Even better, you can use a list comprehension:

with open("I:/my500.csv") as f:
    symbols = [row.rstrip('\n') for row in f]
