Why its dont work?

Hello! I am a python beginner. I write a code, with pyowm module (Pyowm on github: https://github.com/csparpa/pyowm), but its for some reason wrong. I has download the pyowm module and I using the terminal for module installation on python 3. My os is Mac OS X Yosemite and the my python version is 3.6.3. I even use Sublime Text 3 as a code editor. What I do wrong? Please help me!
My code:
   
    import pyowm
   
    city = input('Write a city for weather analysis:')
   
    owm = pyowm.OWM('5f28df836a35fc458e6270eb8f01ec86')
    observation = own.weather_at_place(city)
    w = observation.get_weather()
    temperature = w.get_temperature('celsius')['temp']
   
    print("The temperature in" + city + "is: " + str(temperature) + "on celsius")

But python say:

Traceback (most recent call last):
  File "untitled.py", line 3, in <module>
    city = input('Write a city for weather analysis:')
  File "<string>", line 1, in <module>
NameError: name 'London' is not defined

Write a city for weather analysis: London
Traceback (most recent call last):
  File "untitled.py", line 3, in <module>
    city = input(str('Write a city for weather analysis:'))
  File "<string>", line 1, in <module>
NameError: name 'London' is not defined.


Thanks!!!

Are you sure you are using python 3? Try inserting:

import sys
print(sys.version)

Open in new window


at the top of the module. What does it print?

I tried and I can confirm what Fermi Paradox suggested. You have launched the script using Python 2. If you want to use Python 2, you have to change the input to the equivalent raw_input. The input in Python 2 reads the string from the input and calls eval to interpret the string. You did type London, and it tries to use the object of that name -- this is the reason why the error is displayed.

So, you want to use Python 3. Fix also your line with observation = ovn... to owm. If you need to use Python 2, try the following:
#!python2
from __future__ import print_function
import pyowm

city = raw_input('Write a city for weather analysis: ')

owm = pyowm.OWM('5f28df836a35fc458e6270eb8f01ec86')
observation = owm.weather_at_place(city)
w = observation.get_weather()
temperature = w.get_temperature('celsius')['temp']

print('The temperature in', city, 'is:', temperature, 'on celsius')

Open in new window

In the later case, you need pip install pyown also for Python 2.
