Python Variable Invalid Syntax

Question

import pywapi
import string
zip = input(" ZIP Code: ")
cs = input("City, State: ")

weather_com_result = pywapi.get_weather_from_weather_com('zip')

print "Weather.com says: It is " + .lower(weather_com_result['current_conditions']['text']) + " and " + weather_com_result['current_conditions'] + ['temperature'] + "F now in" ['cs'] + "./n/n"

It gives me an error with 'cs'. Anyone know why?

Answer 1

Change your print statement like below (I mean the format) instead of using string concat operation. I would not say its not correct to write that way but the below way is always a better operation since you will have the control on string type as well.

import pywapi
import string
zip = input(" ZIP Code: ")
cs = raw_input("City, State: ")

weather_com_result = pywapi.get_weather_from_weather_com('zip')

print "Weather.com says: It is %s and %s F now in %s \n \n." %(str(lower(weather_com_result['current_conditions']['text'])), str(weather_com_result['current_conditions']['temperature']), str(cs))

However if you still need it in the concat way use the below sample syntax.

import pywapi
import string
zip = input(" ZIP Code: ")
cs = raw_input("City, State: ")

weather_com_result = pywapi.get_weather_from_weather_com('zip')
print "Weather.com says: It is ." + str.lower('abc') + " and " + 'def' + 'ghi' + "F now in " + str('ijk') + ".\n\n"

Errors in your program

Your print statement has a variable

weather_com_result['current_conditions'] + ['temperature'] it should be weather_com_result['current_conditions']['temperature']

Let me know if you have any questions.

Answer 2

You must replace ['cs'] with + cs.

For the formatting, you can use the % syntax. Then, you will not have errors like this.
