以下是Python代码实现:
```python
t1=(11,22,33,44,55,66)
t2=(t1[3], t1[4])
print(t2)
```
输出结果为:
```
(44, 55)
```

Use map() to return the largest element of each pair (tuple) in the list below: pairs = [(7,5),(1,2),(5,2),(9,1),(4,7)]
Sure, here's the code to use map() to return the largest element of each pair (tuple) in the given list:
```python
pairs = [(7,5),(1,2),(5,2),(9,1),(4,7)]
result = list(map(lambda x: max(x), pairs))
print(result)
```
Output:
```
[7, 2, 5, 9, 7]
```
Here, we have used the `max()` function with `lambda` function to find the maximum element in each tuple of the list. Then, we have converted the result into a list using the `list()` function. Finally, we have printed the result.
Create a new file singleton_tuple.py . Copy the following code and paste it into the file. Print out the type of singleton_tuple and singleton . What difference did you notice? singleton_tuple = ("apple",) singleton = ("apple")
Certainly! Here is the code you requested:
```python
singleton_tuple = ("apple",)
singleton = ("apple")
print(type(singleton_tuple))
print(type(singleton))
```
After running the code and printing the types of `singleton_tuple` and `singleton`, you will notice the following difference:
- The type of `singleton_tuple` is `tuple`. This is because it is defined with a trailing comma, indicating that it is a tuple with a single element.
- The type of `singleton` is `str`, not a tuple. This is because it does not have a trailing comma and is interpreted as a string instead.
The trailing comma in `singleton_tuple = ("apple",)` is crucial to differentiate it from a string. In Python, a tuple with a single element requires a comma after the element to be recognized as a tuple. Otherwise, it will be treated as a different type, such as a string in this case.
