Strange behavior with len and str.splitlines ()
I am making an HTTP request using requests and I want to create a simple response object that parses my data. The problem I am facing is as follows. When passing a response object to the ApiResponse, I split the Response.text in strings to count them and see if it has multiple or single strings. the problem is the split list gives me an error when applying len () to this, but in the console it works fine.
This is the class:
class ApiResponse(object):
pattern = re.compile(r'([a-zA-Z]+): ([a-zA-Z0-9]+)') # original ([a-zA-Z]+)\: ([a-zA-Z0-9]+)
response_type = ResponseType.OK
response_mode = ResponseMode.SINGLE
def __init__(self, r: resp):
self.r = r
self.parse(r)
self.data = None
def parse(self, r: resp):
"""
Method that parses the response from the API
:param r:Response
"""
if r.status_code != 200:
self.response_type = ResponseType.ERR
if len(r.text.splitlines()) > 1:
self.response_mode = ResponseMode.MULTI
for line in r.text.splitlines():
match = self.pattern.search(line)
if match is None:
break
print(match.group(1, 2)) # REMOVE testing
self.response_type = ResponseType[match.group(1)]
This is the console output:
>>> import sys
>>> print(sys.version)
3.4.2 (default, Oct 8 2014, 13:08:17)
[GCC 4.9.1]
>>> import requests
>>> from clickapy.response import ApiResponse
>>> r = requests.get(API_URL, {'user': USER, 'password': PASS, 'api_id': API_ID})
>>> api_response = ApiResponse(r)
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "/home/eefret/PycharmProjects/clickapy/clickapy/response.py", line 32, in __init__
self.parse(r)
File "/home/eefret/PycharmProjects/clickapy/clickapy/response.py", line 43, in parse
if len(r.text.splitlines()) > 1:
TypeError: object of type 'builtin_function_or_method' has no len()
>>> len(r.text.splitlines())
1
Why is this happening? It doesn't make sense to me, I am following the same code snippets, welcome any help or feedback.

A friend of mine (all credits ) helped me and since he doesn't have an SO account, I'll post what solved this behavior, my console was applying , but internally the text had to be encoded anyway, so solved it by changing this to this Mariano Garcia
utf-8
if len(r.text.splitlines()) > 1:
if len(r.text.encode("utf-8").splitlines()) > 1:
