Pass data one function to another function

i want to get the insert() function data in find() function.

n=int(input("Enter choice: "))

if n==1:
  def insert():
    data=['oop','java','python']
    print(data)
    
    return data

  insert()

elif n==2:
  def find():
    data.insert(1,"hi")
    print(data)

  find()

after pressing 2 final output should be

 ['oop','hi','java','python']

Try this -

n=int(input("Enter choice: "))
data = ['oop', 'java', 'python']
if n==1:
  def insert():
    print(data)
    return data
  insert()

elif n==2:
  def find():
    data.insert(1,"hi")
    print(data)

  find()

Output - ['oop', 'hi', 'java', 'python']

To use list locally:

n = int(input("Enter choice: "))

def insert():
    data = ['oop', 'java', 'python']
    return data

def find():
    data = insert()
    data.insert(1, "hi")
    return data

if n==1:
    print(insert())
elif n==2:
    print(find())

Output:

>> Enter choice: 2
['oop', 'hi', 'java', 'python']
>> Enter choice: 1
['oop', 'java', 'python']

EDIT: I didn' read your desired output.

Not sure if this is what you need:

n=int(input("Enter choice: "))

def insert():
    data=['oop','java','python']
    print(data)
    return data

def find():
   def find():
   data_func = insert()
   data_func.insert(1, "hi")
   print(data_func)

if n==1:
    insert()

elif n==2:
    find()

You can't declare funcions inside a conditional "if" since if your input is 2 you will never execute inset() funcion and data variable will never be declared.

Also you should name your functions in different way from python predefined methods...

regards.

You need to understand how scope works in Python. You can read about it here https://realpython.com/python-scope-legb-rule/ but a basic understanding is that variables declared in a function is only local to that function. What you probably need to do is to pass the data array to both functions to Keep the scope of the variable.
