Python - what is the difference between my_file.read() and reader(my_file)

Question

Hi!

Sololearn is using read() method for opening files. On one another site for learning Python,, they are using reader() object.
What is the difference, when can i use one method and when should I use another method

Code;
file = open("filename.txt", "r")
cont = file.read()
print(cont)
file.close()

from csv import reader
oppened_file = open('AppleStore.csv')
read_file = reader(oppened_file)
apps_data=list(read_file)

Thx!

Answer 1

Look at the file extensions. One is for plain text files, the other for csv files.

Btw, "with open(file, "r") as f:" is preferable to just open(file, "r"). The former makes sure that the file gets closed again (whatever happens).

Thoq!, thank you very much!
