Python 3.6.5 syntax error in IDLE

[snippsat]

You can not have text from IDLE/REPL which is interactive testing in a script.
In a script there is no >>> or start text of REPL Python 3.6.5 (default, Jan 16 2019, 21:12:16).

To show how it work as script,also a .py file.

# names.py
import csv
from pprint import pprint

pprint(dir(csv)) # display the contents of the csv module
['Dialect', 'DictReader', 'DictWriter',
'Error', 'OrderedDict', 'QUOTE_ALL', 'QUOTE_MINIMAL', 'QUOTE_NONE',
'QUOTE_NONNUMERIC', 'Sniffer', 'StringIO', '_Dialect', '__all__',
'__builtins__', '__cached__', '__doc__', '__file__', '__loader__',
'__name__', '__package__', '__spec__', '__version__', 'excel',
'excel_tab', 'field_size_limit', 'get_dialect', 'list_dialects', 're',
'reader', 'register_dialect', 'unix_dialect', 'unregister_dialect',
'writer']

print('-'*20)
path = 'names.csv'
file = open(path, newline = '')
reader = csv.reader(file)
header = next(reader)
data = [row for row in reader]

print(header)
print(data[0])

Output:
E:\div_code\egg
λ python names.py
['Dialect',
 'DictReader',
 'DictWriter',
 'Error',

 'QUOTE_ALL',
 'QUOTE_MINIMAL',

 'writer']
--------------------
['first_name', 'last_name', 'email']
['John', 'Doe', '[email protected]']

If i start REPL eg ptpython interact shell,and do first part it look this.

E:\div_code\egg
λ ptpython
>>> import csv

>>> dir(csv)[:10]
['Dialect', 'DictReader', 'DictWriter', 'Error', 'OrderedDict', 'QUOTE_ALL', 'QUOTE_MINIMAL', 'QUOTE_NONE', 'QUOTE_NONNUMERIC', 'Sniffer']

See now is >>> there,and command get executed bye Enter.
