Python Exercise: Calculate the number of upper / lower case letters in a string

Python Functions: Exercise-7 with Solution

Write a Python function that accepts a string and calculate the number of upper case letters and lower case letters.

Sample Solution:-

Python Code:

def string_test(s):
    d={"UPPER_CASE":0, "LOWER_CASE":0}
    for c in s:
        if c.isupper():
           d["UPPER_CASE"]+=1
        elif c.islower():
           d["LOWER_CASE"]+=1
        else:
           pass
    print ("Original String : ", s)
    print ("No. of Upper case characters : ", d["UPPER_CASE"])
    print ("No. of Lower case Characters : ", d["LOWER_CASE"])

string_test('The quick Brown Fox')

Sample Output: 

Original String :  The quick Brow Fox                                                                         
No. of Upper case characters :  3                                                                             
No. of Lower case Characters :  13

Python: Tips of the Day

Decapitalizes the first letter of a string:

Example:

def tips_decapitalize(s, upper_rest=False):
  return s[:1].lower() + (s[1:].upper() if upper_rest else s[1:])
print(tips_decapitalize('PythonTips'))
print(tips_decapitalize('PythonTips', True))

Output:
