No. of Upper case characters: 3

No. of Lower case characters: 13

str=input("Enter a string\n")

up=0

lw=0

for i in str:

 if i.isupper():

  up=up+1

 elif i.islower():

  lw=lw+1

 else:

  pass

print("No. of Upper case characters: ",up)

print("No. of Lower case characters: ",lw)

 Program Output :

from time import strftime

 

root = Tk()

root.title('Clock')

 

def time():

    string = strftime('%H:%M:%S %p')

    lbl.config(text=string)

    lbl.after(1000, time)

 

lbl = Label(root, font=('calibri', 30, 'bold'),

            background='red',

            foreground='white')

 

lbl.pack(anchor='center')
