How to output the entire contents of an array to a file?

Question

Python

There is such a code in python, I wanted to display all the contents in the console, but the text does not fit there, so I had to write the contents to a file. But only the last element of the list is written to the file, and you need to output all 121. How to do this? I will be very grateful

i = 0
while(i <= 121):
    val = "elif call.data == \"f{0}\": \n \
        FILTER[user_id] = '{1}' \n \
        msg = bot.send_message(call.message.chat.id, \"Выбран стиль {0}.\") \n \
        bot.register_next_step_handler(msg, load) \n \
        bot.edit_message_reply_markup(call.message.chat.id, call.message.message_id, reply_markup = None) \n  \
    ".format(i, list[i+1])
    f1 = open("D:/text1.txt", 'w')
    f1.write(val)
    i += 1

Answer 1

You are overwriting the file each time by passing the 'w' argument. Of course there will be only the last line
f1 = open("D:/text1.txt", 'w')

s = 'elif call.data == "f{0}": \n \
            FILTER[user_id] = \'{1}\' \n \
            msg = bot.send_message(call.message.chat.id, "Выбран стиль {0}.") \n \
            bot.register_next_step_handler(msg, load) \n \
            bot.edit_message_reply_markup(call.message.chat.id, call.message.message_id, reply_markup = None) \n  \
        '

with open('D:/text1.txt', 'a') as f:
    for i, value in enumerate(list[1:]):
        f.write(s.format(i, value))

Opening a file for every line is a very costly operation. Not to mention that you do not even close it, which will potentially lead to underwriting. Correctly work with files through context managers:

i = 0

with open("D:/text1.txt", "w") as f1:
    while i <= 121:
        val = 'elif call.data == "f{0}": \n \
            FILTER[user_id] = \'{1}\' \n \
            msg = bot.send_message(call.message.chat.id, "Выбран стиль {0}.") \n \
            bot.register_next_step_handler(msg, load) \n \
            bot.edit_message_reply_markup(call.message.chat.id, call.message.message_id, reply_markup = None) \n  \
        '.format(
            i, list[i + 1]
        )
        f1.write(val)
        i += 1

Answer 3

instead of w in open put a
in this case w overwrites the file. a -- flag for adding content.
