Hi, can any one show me how to do this test task, I'm learning how to read, write e.t.c files

Question

The task is this

You are given the following list:
names= ["John", "Oscar", "Jacob"]

Complete the program to create a file in which you write the names of the list, each one on a new line, and output them separately.

Output:
John
Oscar
Jacob

Remember that "\ n" represents a new line.

I'm not so familiarize with the functions for read and write, i know to do some things but I don't fully understand how everything works, let say i know all the the functions but I don't know how to make everything work together.

If anyone can help I'll appreciate it

Answer 1

this might help!

with open("test.txt","w") as file:
file.writelines(["a\n","b"])

with open("test.txt","r") as file:
print("".join(file.readlines()))

or you can read the file immediately after writing to it .

with open("test.txt","w+") as file:
file.writelines(["a\n","b"])
file.seek(0)
print("".join(file.readlines()))

______________________________
seek will make the file pointer point to the start of it .
"w+" is for reading and writing .

Answer 2

Thanks Abhay in the test code play ground give me this code:

names = ["John", "Oscar", "Jacob"]

file = open("names.txt", "w+")
#wrrite the names on the file
file.close()

file= open("names.txt", "r")
#output file content to console
file.close()

Answer 3

anthony silver with open works the same as file=open
and file.close() but in with open statement you don't have to explicitly call the close method , it does it by itself .

Answer 4

Ok

Answer 5

Abhay Can you tell me if it s necessary that I use the code that the task gave me, or can I use your code and the other code together, or only your code? Sorry I'm a little bit lost

Answer 6

anthony silver it would be better to go with what initial code sololearn gave you but there is no rule for that . You can use my as well .

And if you still don't understand anything in my code , feel free to ask !!

Answer 7

Abhay so when I make the code i put only open without an equal mark or without a dot or with a dot?
