Explanation / Answer

a = input("Enter a string:")
print("string entered: ",a)
#a
#printing
#Only the uppercase letters in the string.
print("printing Only the uppercase letters in the string.")
for i in a:
if(ord(i)>=65 and ord(i)<=90):
print(i,end='')
print(" ")
#b
#Every second letter of the string.
n =a
l = n.split(' ')
print('printing Every second letter of the string')
for i in l:
if(len(i)>1):
print(i[1])

#c
#The string, with all vowels replaced by an underscore.
print("printing vowels replaced by underscore:")
for i in a:
if(i=='u' or i=='U' or i=='o' or i=='O' or i=='i' or i=='I' or i=='e' or i=='E' or i=='a' or i=='A'):
print('_',end='')
else:
print(i,end='')
print(" ")
#d
#The number of digits in the string.
print("The number of digits in the string: ",end='')
c=0
for i in a:
if(ord(i)>=48 and ord(i)<=57):
c+=1#counting numbers
print(c)
#e
#The positions of all vowels in the string.
print("The positions of all vowels in the string: ");
cc=0
for i in a:
if(i=='u' or i=='U' or i=='o' or i=='O' or i=='i' or i=='I' or i=='e' or i=='E' or i=='a' or i=='A'):
print(cc,' ',end='')
cc+=1
print(" ")

output:
