Two questions:1, Strings is more similar with tuple ? 2, Why is false ?

Question

1,
Lists and strings are similar in many ways - strings can be thought of as lists of characters that can't be changed.

2,
The in operator is also used to determine whether or not a string is a substring of another string.

A=["spam",["eggs","sandwich"]]
Print ("eggs" in A)
-> false
Print ("eggs" in A[1])
-> true

Why???

Answer 1

Answer to your second question,
the list A has two elements "spam" and ["eggs","sandwich"] ,if u execute "eggs" in A it returns false because in is membership operator and A do not have any element "eggs" in it. **in compares the elemets as a whole **

Answer 2

A string stores characters only (despite of encoding)
A tuple stores any type, including (among which) tuples, strings and other types.
