How can I output “abc” in order of size using Python?

You can sort a string using the sorted function, then use a for loop to output each character one by one. Here is an example code:

string = "abc"
sorted_string = sorted(string)
for char in sorted_string:
    print(char, end="")

The result of the operation is:

abc

Additionally, if you want to output the string in reverse order, you can use the parameter reverse=True in the sorted function. Sample code is as follows:

string = "abc"
sorted_string = sorted(string, reverse=True)
for char in sorted_string:
    print(char, end="")

The result of the operation is:

cba
