In Python, the reverse() function is mainly used for list and string inversions. This function will modify the original list or string directly, rather than creating a new inverted object.
1.reverse() of the list
In Python, the reverse() function of the list is used to invert the elements in the list. This function will directly modify the original list, rather than creating a new inverted list. Here's a simple example:
It should be noted that the reverse() function will directly modify the original list, if you don't want the original list to be modified, you can copy a list and then reverse it.
2.reverse() of the string
For strings, python doesn't provide a reverse() function. However, we can use slices to invert strings. Here's an example:
In this example, we use the slice operator [::1] to invert the string. The meaning of this operator is "take from back to front in steps of -1", which means to reverse. It should be noted that the slicing operation will create a new string, and the original string will not be modified.
In Python, the reverse() function is mainly used for inversions of lists and strings. For lists, you can use the reverse() function directly to invert the elements;For strings, you can use the slice operator [::1] to achieve inversion. It should be noted that the reverse() function will directly modify the original object, and if you need to keep the original object, you need to make a copy before reversing it.
