Hi everyone: I’m looking at this case of nested loops.
Write a programme that reads a word and prints all substrings, sorted by length. For example, if the user provides the input “rum”, the programme prints:
r
u
m
ru
um
rum
I have this:
##
# Display all substrings of a word, sorted by length.
#
# Read the word from the user.
word = input("Enter a word: ")
# Generate and display all substrings ordered by increasing length.
for length in range(1, len(word) + 1) :
for pos in range(0, len(word) - length + 1) :
print(word[pos : pos + length])
I print everything, but don’t know what the numbers after the second A are referring to or why the formula in the nested loop looks so cryptic:
word = input("Enter a word: ")
# Generate and display all substrings ordered by increasing length.
for length in range(1, len(word) + 1) :
for pos in range(0, len(word) - length + 1) :
print(len(word) - length + 1)
print(length + 1)
print(word[pos : pos + length])
Enter a word: Ana

A
