For which of the following statements will the variable s contain a string data type after it is executed?

Transcribed Image Text:```python
s = "3.14159"
s = input("Enter an integer:")
s = "3.14159" + 3
s = "3.14159" + "3"
s = str(3.14159)
s = print(3.14159)
```
### Explanation
1. **String Assignment**:
- `s = "3.14159"`: Assigns the string "3.14159" to the variable `s`.
2. **User Input**:
- `s = input("Enter an integer:")`: Prompts the user to enter an integer. The input is stored as a string in `s`.
3. **String and Integer Concatenation**:
- `s = "3.14159" + 3`: Attempts to add the integer `3` to the string `"3.14159"`. This will cause a TypeError since you cannot directly concatenate a string and an integer in Python.
4. **String Concatenation**:
- `s = "3.14159" + "3"`: Concatenates the strings `"3.14159"` and `"3"` resulting in the string `"3.141593"`.
5. **Convert Float to String**:
- `s = str(3.14159)`: Converts the float `3.14159` to a string and assigns it to `s`.
6. **Print Function Assignment**:
- `s = print(3.14159)`: Prints the number `3.14159` to the console and assigns the result of `print()`, which is `None`, to `s`.
