Answer 1

Q1)

user_str = input('Enter in your string')
count = 0
# split the string into words, space separator
words = user_str.split(' ')
# counting the number word 'the'
for word in words:
    if word ='the':
        count += 1
print(count)

Q2)

user_str = input('Enter in your string')
count = 0
# split the string into words, space separator
words = user_str.split(' ')
for word in words:
# do not count the space as a word
    if word != '':
        count += 1
print(count)

Q3)

user_str = input('Enter in your string')
user_word = input('Enter in your word')
position = 0
# split the string into words, space separator
words = user_str.split(' ')
for word in words:
# the position of the word in the string, excluding spaces
    if word != '':
       position += 1
# print positions of the selected word on one line separated by a space
    if word == user_word:
        print(position, end=' ')
