is there a default to .insert new data to existing list ?

Example:

thislist = ["apple", "banana", "cherry"]
thislist.insert(2, "watermelon") #i used 2 as index and passed watermelon as new data to list and it will take position of cherry
print(thislist) 

it returns error when i try it this way :

thislist = ["apple", "banana", "cherry"]
thislist.insert(, "watermelon")
print(thislist)

txt = "Hello, And Welcome To My World!"
x = txt.casefold()

print(x)


txt = "Hello, And Welcome To My World!"
y = txt.lower()

print(y)

What's the difference between function casefold() and .lower ?
