Python 3.6.5 syntax error in IDLE

[loren41]

Trying to use IDLE in Python 3.6.5 but receiving sytax error at the top line.

Python 3.6.5 (default, Jan 16 2019, 21:12:16) 
[GCC 7.3.0] on linux
Type "copyright", "credits" or "license()" for more information.
>>> import csv
>>> with open('/home/bob/Python_data_sets/names.csv', 'r') as csv_file:
	csv_reader = csv.reader(csv_file)
        for line in csv_reader:
                print(line)

Syntax error highlights the number 6 in the first line when I run "Check Module." Any thoughts?

This question is better directed to the authors of python and idle at https://bugs.python.org/

Is this the content of your .py file?
Or is this an interpretter session?
And if it's interpretter session then what "top line" do you actually mean? "import csv"?

To me it looks like you copied the contents of interpretter session into ".py" file and that is the reason why the error occurs.

The actual code (extracted from your post) that should be put into the ".py" file is:

import csv
with open('/home/bob/Python_data_sets/names.csv', 'r') as csv_file:
	csv_reader = csv.reader(csv_file)
    for line in csv_reader:
        print(line)

(didn't test it though)

Tried a code example in IDLE first. Then tried a second example using Sublime Text. Same error, but more feedback.

Error info appeared as follows:

Have no idea what the problem is.

Can you post the contents of the CSV_module.py file?

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',
 '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']
--------------------
['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.
