Ok so I have the following code:
def rate_of_work(self):
global rate
rate = (turtle.textinput("Your Work Rate","What is your hourly work rate in US Dollars?"))
outFile_rate = pickle.dumps(rate)
rate1 = pickle.loads(rate)
rate2 = ((hours*rate1) + (minutes*rate1)*0.0167 + (seconds*rate1)*0.000278) #isnt necessary information
rate3 = round(rate2, 2) #isnt necessary information
im getting the error:
rate1 = pickle.loads(rate)
TypeError: 'str' does not support the buffer interface
please help
I assume you are working under python 3.x
For the specific error, pickle.loads() only accepts bytes, and you are trying to give a plain string to it, that's why it fails.
>>> pickle.loads("")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'str' does not support the buffer interface
>>> pickle.loads(b"")
Traceback (most recent call last):

I am trying to open and load pickle file but by two ways. But every time I am getting an error.
Request you to please help.
First way :
enron_data = pickle.load(open("D:/New/ud120-projects/final_project/final_project_dataset.pkl", "r"))
Error: Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: a bytes-like object is required, not 'str'
Second Way :
enron_data = pickle.load(open("D:/New/ud120-projects/final_project/final_project_dataset.pkl", "rb"))
Error : Traceback (most recent call last):
File "<stdin>", line 1, in <module>
_pickle.UnpicklingError: the STRING opcode argument must be quoted
Request you to please help
If you are on Windows you have to use a raw string and backslashes like this:
r'D:\path\to\your\file'
I have never split strings in Python before so I am not too sure what is going wrong here.
import pyowm
owm = pyowm.OWM('####################')
location = owm.weather_at_place('Leicester, uk')
weather = location.get_weather()
weather.get_temperature('celsius')
temperature = weather.get_temperature('celsius')
print(temperature[5:10])
Error received
sudo python weather.py
Traceback (most recent call last):
File "weather.py", line 10, in <module>
print(temperature[5:10])
TypeError: unhashable type
get_temperature returns a dictionary, which you're then trying to index with a slice object, which is not hashable. e.g.
>>> hash(slice(5, 10))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: unhashable type
To get the temperature, you need to get it from the dictionary like this:
temperature['temp']
I tried to run a test on Crab(an open source recommender system) based on python3. Then an error occurred:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/Dennis/anaconda/lib/python3.5/site-packages/scikits/crab/datasets/base.py", line 201, in load_sample_movies
data_songs[u_ix][i_ix] = float(rating)
ValueError: could not convert string to float: "b'3.0'"
I tried to use 'decode()' to convert the string, but it's not working:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/Dennis/anaconda/lib/python3.5/site-packages/scikits/crab/datasets/base.py", line 202, in load_sample_movies
rating = rating.decode('utf-8')
AttributeError: 'numpy.str_' object has no attribute 'decode'
Any help will be appreciated!
The problem is that rating is a string within a string, so when you try casting a string like "b'3.0'" into a float, it gives a valueError because you still have the b in front which cannot be converted into float.
I imagine you need the byte encoding in front of the '3.0', so one way would be to evaluate rating to convert it from a string to bytes before typecasting it into a float (beware though, eval can have some safety issues).
>>> type(eval(rating))
<class 'bytes'>
>>> data_songs[u_ix][i_ix] = float(eval(rating))
Need to import data from the ISS.
Use the code
r= urllib.request.urlopen('http://www.celestrak.com/NORAD/elements/stations.txt')
x=r.read(1000)
when I try to split the data with
x=x.split("\r\n")
I get the error
raceback (most recent call last):
File "<pyshell#26>", line 1, in <module>
x=x.split("\r\n")
TypeError: a bytes-like object is required, not 'str'
How can I fix this?
Why not just use requests?
import requests
response = requests.get("http://www.celestrak.com/NORAD/elements/stations.txt")
text = response.text.split("\r\n")
for t in text:
print t
I'm trying to use PyKDE, PyKDE.kdecore.KStandardDirs to be precise. This method is called with two strings according to the documentation and according to the PyQt4 documentation, I can use standard Python strs instead of QString.
This doesn't work:
>> KStandardDirs.locate()("socket", "foo")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: KStandardDirs.locate(): not enough arguments
>>> KStandardDirs.locate("socket", "foo")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: KStandardDirs.locate(): argument 1 has unexpected type 'str'
I can't use QString either because it doesn't seem to exist:
>>> from PyQt4.QtCore import QString
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name QString
>>> from PyQt4.QtCore import *
>>> QString
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'QString' is not defined
What am I doing wrong?
I suspect that PyKDE is not yet Python 3 ready, at least as far as that error message is concerned; try passing in a bytestring instead:
KStandardDirs.locate(b"socket", "foo")
