Functions not working

#1

During the lecture I have created the functions but those functions are not working. Below are the codes I wrote please advise , nothing comes at output.

def addtwo(a,b):
added = a + b:
return added
x = addtwo(2 , 3)
print(x)

Other one

def thing():
x = int(input('enter x '))
y = int(input('enter y '))
print(x)
print(y)
if x > 0 and x < 10 or y > 10 and y < 20:
print(‘yes’)

else:
    print('no')

print ('yes')

and last one

def greet(lang):
if lang == ‘fr’:
print(‘bonjour’)
elif lang == ‘es’:
print(‘hola’)
else:
print(‘hello’)

error for same is
greet(fr)

NameError Traceback (most recent call last)
in
----> 1 greet(fr)

NameError: name ‘fr’ is not defined

#2

First program

def addtwo(a,b):
added = a + b # you have given colon here.
return added
Second and third program are absolutely correct!
Just run it using suitable test cases.

All the best!

@Akshit_Jain

Please use greet("fr") instead of greet(fr).

#4

Program was correct but you were giving wrong input greet(“fr”) as you have written logic for “fr” not fr.
