Sure, here are three ways in which lists and strings are not alike in Python:

1. Mutability:
Strings are immutable in Python, which means we cannot change an existing string. However, lists are mutable, which means we can change an item in a list using the index operator.

Example:
```python
# For string
s = "Hello"
s[0] = 'Y' # This will raise an error

# For list
l = ['H', 'e', 'l', 'l', 'o']
l[0] = 'Y' # This will not raise an error
```

2. Methods:
Strings and lists have different methods. For example, the `join()` method is available for strings but not for lists, and the `append()` method is available for lists but not for strings.

Example:
```python
# For string
s = "Hello"
s = s.join(" World") # This will not raise an error

# For list
l = ['H', 'e', 'l', 'l', 'o']
l = l.join(" World") # This will raise an error
```

3. Operators:
Some operators behave differently with strings and lists. For example, the '+' operator concatenates strings and merges lists.

Example:
```python
# For string
s1 = "Hello"
s2 = " World"
s = s1 + s2 # This will return "Hello World"

# For list
l1 = ['H', 'e', 'l', 'l', 'o']
l2 = [' ', 'W', 'o', 'r', 'l', 'd']
l = l1 + l2 # This will return ['H', 'e', 'l', 'l', 'o', ' ', 'W', 'o', 'r', 'l', 'd']
```
