To sort a string in descending order, you can use the following function:
def sort_string(string):
# Convert the string to a list of characters
char_list = list(string)
# Sort the list in descending order
char_list.sort(reverse=True)
# Join the list of characters back into a string
sorted_string = ''.join(char_list)
return sorted_string
This function first converts the input string to a list of characters. It then sorts the list in descending order using the sort
method and the reverse
parameter. Finally, it joins the list of characters back into a string using the join
method.
For example, if you call sort_string('abddccss')
, the function will return 'ssddccba'
.
Note that this function is not case-sensitive, so if you call sort_string('AbddcCSS')
, it will still return 'ssddccba'
. If you want to preserve the case of the original string, you can modify the function to sort the list of characters using the key
parameter and a custom function that returns the lowercase version of a character.
For example:
def sort_string(string):
# Convert the string to a list of characters
char_list = list(string)
# Sort the list in descending order, preserving the case of each character
char_list.sort(key=lambda x: x.lower(), reverse=True)
# Join the list of characters back into a string
sorted_string = ''.join(char_list)
return sorted_string
This modified function will sort the string in descending order, preserving the case of each character. For example, if you call sort_string('AbddcCSS')
, it will return 'SSddcCBA'
.
