好的,下面是一个可以将字符串反转的函数的 Python 代码:
```
def reverse_string(s):
return s[::-1]
```
该函数将字符串作为参数传入,并通过步长为 -1 的切片操作对字符串进行反转,最后返回反转后的字符串。例如:
```
>>> reverse_string("hello world")
'dlrow olleh'
```

Question 3.2: Write a Python function named "reverse_string" that takes a string as input and returns the reverse of the input string.
Sure, here's a Python function named "reverse_string" that takes a string as input and returns the reverse of the input string:
```python
def reverse_string(s):
# Use slicing to reverse the string
return s[::-1]
```
This function takes a string `s` as input and returns the reverse of the string using slicing. The `[::-1]` notation is a slice that starts at the end of the string and ends at the beginning of the string, with a step of -1 (i.e., it goes backwards). This effectively reverses the string.
Here's an example of how to use the function:
```python
s = "hello world"
reversed_s = reverse_string(s)
print(reversed_s) # prints "dlrow olleh"
```
In this example, we pass the string "hello world" to the `reverse_string` function and assign the result to the variable `reversed_s`. We then print `reversed_s`, which should be the reverse of the input string.

Sure! Here is the Python function named "reverse_string" that takes a string as input and returns the reverse of the input string:
```python
def reverse_string(input_string):
return input_string[::-1]
```
This function uses Python slicing to reverse the input string. The `[::]` notation means to start at the end of the string and step backwards by one character until the beginning of the string is reached. This effectively reverses the string.
