I need to read 100000 lines of a txt file and add each line into a array

Question

I have a TXT file which contains 100000 lines of short strings from 1-3 digits long. I need a for loop that loops 100000 times, and in the loop I need to read a line then add it to an array and finally move down to the next line. The txt file is called Rand_Numbers and I have opened it as...

C_txt = open("Rand_Numbers", "r")

I don't really know how to do much in python as i'm fairly new to the programming scene. Any help is much appreciated.

I think this [question](https://stackoverflow.com/questions/3277503/how-to-read-a-file-line-by-line-into-a-list) is the same as yours. — chluebi, Dec 28 '19 at 18:45
`with open('ur_file.txt') as f: list_of_ints=[int(e) for e in f]` — dawg, Dec 28 '19 at 18:47

welcome to Python. how about

dump_here = []
with open('your_file.txt') as my_file:
    for line in my_file:
        dump_here.append(line)

You don't need `my_file.close()` that's the whole point of the context manager. Also, you can just do `dump_here = list(my_file)` – juanpa.arrivillaga Dec 28 '19 at 19:09
