Hi , I am new to Python and I am not sure what I am doing wrong here, anythig I type I only get the first "print" out. Any help very appreciated.
fav_colour = input('Which colour do you like? ')
if fav_colour == 'Blue' or 'blue':
print('I like this colour ')
elif fav_colour == 'white':
print('I still prefer blue')
elif fav_colour == 'yellow':
print('this is gold colour')
else:
print('colour only')
#!/usr/bin/env python3
fav_colour = input('Which colour do you like? ')
if fav_colour == 'Blue' or fav_colour == 'blue':
print('I like this colour ')
elif fav_colour == 'white':
print('I still prefer blue')
elif fav_colour == 'yellow':
print('this is gold colour')
else:
print('colour only')
#!/usr/bin/env python3
Color = {}
Color['Blue'] = 'I like this colour'
Color['blue'] = 'I like this colour'
Color['white'] = 'I still prefer blue'
Color['yellow'] = 'this is gold colour'
count = 0
while count >= 0:
x = input('Which colour do you like ')
y = str(Color.get(str(x)))
if y == str('None'):
print('colour only')
else:
print (y)
print('')
answer = input('Do you want to go again? Y or any character to end ')
if answer == 'Y' or answer == 'y':
count += 1
else:
count == -1
print('')
print('sorry to see you go')
You can do a dictionary with an non-listed colour statement and a return

Which colour do you like Brown
colour only
Do you want to go again? Y or any character to end y
Which colour do you like green
colour only
Do you want to go again? Y or any character to end y
Which colour do you like white
I still prefer blue
Do you want to go again? Y or any character to end y
Which colour do you like blue
I like this colour
Do you want to go again? Y or any character to end y
Which colour do you like Blue
I like this colour
Do you want to go again? Y or any character to end j
sorry to see you go
Which colour do you like
@Michael-McKenney Brilliant, I see what I did wrong, amazing you still provided another example, Thank you so much Sir. 
@Claudio-Nogueira
The reason that you are seeing the result for only the first if statement is the or 'blue' condition. When you have this, Python sees this as or True which will always evaluate with True. If you change or 'blue' with or fav_colour == 'blue' then you should see a change.
@Justin-Dennison66 Thanks Justin for the detailed explanation or what I did, really appreciate it. It is good to see it and start "getting taste for programming", still long way to go but I am start enjoying it. Thank you so much Sir.
@Claudio-Nogueira No problem. I started reading an intermediate book. I will do it as a class next.
Here is another way using class
#!/usr/bin/env python3
class ColorPick:
def __init__(self, color, output='just another colour'):
self.color = color
self.output = output
def Blue(self):
print("Blue, I like this colour")
def blue(self):
print("blue, I like this colour")
def white(self):
print("white, I still prefer blue")
def yellow(self):
print("yellow, this is gold colour")
def notyourcolor(self):
print(x_color, "just another color")
class Pick(ColorPick):
pass
retry = 0
while retry == 0:
count = 0
x_color = input("what color do you choose? ")
if x_color == 'blue' and count == 0:
yourcolor = Pick(x_color)
yourcolor.blue()
count = 1
elif x_color == 'Blue' and count == 0:
yourcolor = Pick(x_color)
yourcolor.Blue()
count = 1
elif x_color == 'white' and count == 0:
yourcolor = Pick(x_color)
yourcolor.white()
count = 1
elif x_color == 'yellow' and count == 0:
yourcolor = Pick(x_color)
yourcolor.yellow()
count = 1
elif count == 0:
yourcolor = Pick(x_color)
yourcolor.notyourcolor()
answer = input('do you wish to go again? Y or y for yes, any other no? ')
if answer == 'Y' or answer == 'y':
retry = 0
print('')
else:
retry = 1
print('')
print('sorry to see you leave')

@Michael-McKenney Fantastic , seeing examples like this shows me that it can get very complex but with a logic behind, which is this logic that I am on my way learning, thank you so much Sir it really opens my mind to a bigger picture of what python is capable of. Honest, python is the first program language I started learning and so far enjoying it
I started with basic and advanced basic in the 1980s. You should learn flow charting to better design code. I start with writing do the idea of what the program does and how it should work.
