Opening file - Answer is correct but error

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

print(len(apps_data))
print(apps_data[0])
print(apps_data[1;3])

Subsequent error message after running code is:
File “”, line 2
opened_file = open('AppleStore.csv)
^
SyntaxError: EOL while scanning string literal

apps_data isn’t defined in your code, but we expected it to be list type

print(apps_data[1;3]) should say apps_data[1:3], you have a semilcolin “;” instead of “:”
