Hint:

Iterate each character from a string and check if the current character is the lower or upper case using islower() string function

Solution:

Create two lists lower and upper
Iterate a string using a for loop
In each loop iteration, check if the current character is the lower or upper case using the islower() string function.
If a character is the lower case, add it to the lower list, else add it to the upper list
to join the lower and upper list using a join() function.
convert list to string
print the final string

str1 = "PYnAtivE"
print('Original String:', str1)
lower = []
upper = []
for char in str1:
    if char.islower():
        # add lowercase characters to lower list
        lower.append(char)
    else:
        # add uppercase characters to lower list
        upper.append(char)

# Join both list
sorted_str = ''.join(lower + upper)
print('Result:', sorted_str)
