How to fix error: SyntaxError: invalid syntax

[Jake Colborn]

Hey, I just picked up python again after not coding with it for many years. But I wanted to throw some simple scripts together to see if I remember all the functionality so far. Now I've got this code:

#!/usr/bin/python

# A program developed to see if the temperature is Celcius or Farhenheit
# and than convert it to the other in a more user friendly manner

import os, sys
import math

def far(temp):
	
	Celcius = ((temp - 32) * 5) / 9
	Kelvin = Celcius + 273.15

def cel(temp):
	
	Far = (temp * 1.8) + 32
	Kelvin = temp + 273.15

def kelvin(temp):

	Celcius = temp + 273.15
	Far = (Celcius * 1.8) + 32


human = raw_input("Is your temperature in Fahrenheit (f), Celcius (c), or Kelvin (k) --> ")
temp1 = int(raw_input("What is your temperature --> ")

if human=="f":
	far(temp1)
	print "Your temperature is %s in Celcius and %s in Kelvin" % Celcius,Kelvin
if human=="c":
	cel(temp1)
	print "Your temperature is %s in Fahrenheit and %s in Kelvin" % Far,Kelvin
if human=="k":
	kelvin(temp1)
	print "Your temperature is %s in Celcius and %s in Fahrenheit" % Celcius,Far

I want the user to define which kind of temperature they have and than the program to output the other temperatures. But so far all I get is an error in the syntax at line 28:

  File "temp2.py", line 28
    if human=="f":
                 ^
SyntaxError: invalid syntax

Anyone have any thoughts?

You have to always check the previous line as well. If you have forgotten a closing parenthesis for example, the interpreter will think that this line is a continuation of the previous line and point to this line with the error. Also consider wrapping the input in a try/except, so if someone enters "F" or "98.6" for the temperature instead of an integer, you can catch it and then ask for a whole number.

##   depending on how much input checking you want to do
human = ""
while human.lower() not in ["c", "f", "k"]:
    human = raw_input("Is your temperature in Fahrenheit (f), Celsius (c), or Kelvin (k) --> ")

## simplified example
try:
    temp1 = int(raw_input("What is your temperature --> "))
except:
    print "The temperature must be a whole number"
