I have this code:
s = 'letter of letters'
for i in s.split(" "):
if len(i) > 4:
s = s.replace(i, i[::-1])
print s
But this prints "rettel of rettels" which means code replace all 'letter' in string, but i need to replace only by every word themself.
How it possible to chagne single word but not all in string? I need 'rettel of srettel'
You need to collect all the modified words separately, instead of modifying the string in your loop:
words = s.split(' ')
results = []
for word in words:
if len(word) > 4:
results.append(word[::-1])
else:
results.append(word)
print(' '.join(results))

I'm coding hangman and the problem I'm facing is that i cant fill in the blanks of the word with the correct location with the letters.
I want to be able to type in a letter and it'll fill in the blank with that letter at the correct location.
code block:
#converts selected word into a array
hidden_word = input('Enter a word ')
List = [m[0] for m in hidden_word]
x = len(hidden_word)
d = [(('_')*x)]
d = "".join(d)
print(d)
#fills in gaps with letter you've guessed
first_guess = input('Guess a letter ')
if first_guess in List:
y = str.find(hidden_word, first_guess)
count = List.count(first_guess)
f = d.replace(d[y],first_guess,count)
print(f)
print('YESS')
else:
print('NOO')

word2 = input("put in the word you want me to repeat: ")
letter = ""
print("The original string is: " + word2)
for x in range(len(word2)):
letter += word2[x]
So if i put in "dwas" it will just print "dwas". How do I make it print "d-ww-aaa-ssss"?
You can use enumerate passing the string value from input, and the start value as 1, then repeat the characters n times, and finally join by -:
>>> print('-'.join(v*i for v,i in enumerate(inp,1)))
d-ww-aaa-ssss
By composiing built-in functions:
s = "hallo"
new_s = '-'.join(map(str.__mul__, s, range(1, len(s)+1)))
print(new_s)
#h-aa-lll-llll-ooooo
A for loop approach similar to the one in the question
s = "hallo"
# construct the output character per character
new_s = ''
# iterate over (index, character)-pairs, index start from 1
for i, char in enumerate(s, 1):
# add to output i-times the same character followed by -
new_s += f'{char*i}-'
# remove the last character (always the -)
new_s = new_s.rstrip('-')
# check result
print(new_s)

This function takes a string as input and returns True if string is palindrome and
False otherwise. A palindrome is a symmetric sequence of characters, reading
the same forward and backward.
For example: radar, anna, mom, dad, …
You can do this like the below:
def is_palindrome(phrase):
string = ""
for char in phrase:
if char.isalnum():
string += char
print(string)
return string[::-1].casefold() == string.casefold()
word = input("Please enter a word to check: ")
if is_palindrome(word):
print("'{}' is a palindrome".format(word))
else:
print("'{}' is not a palindrome".format(word))

def spin_words(sentence):
# Your code goes here
return " ".join([x[::-1] if len(x) >= 5 else x for x in sentence.split(" ")])
I don't understand this one.
sentence.split(" ") gets all the words in the sentence input parameter by separating when it finds a whitespace.
for x in sentence.split(" ") applies the loop to each word resulting from the previous statement
x[::-1] if len(x) >= 5 else x reverses the word if its length is greater than 5
return " ".join returns the result of the previous statement, joining the words with whitespaces

I want to write a python function that accepts a hyphen separated sequence of colors as input and returns the colors in a hyphen separated sequence after sorting them alphabetically
constraint: All colors will be completely in either lower case or upper case
sample input: green-red-yellow-black-white
sample output: black-green-red-white-yellow
My code -
my_str = input("Enter a string: ")
words = [word.lower() for word in my_str.split()]
words.sort()
print("The sorted words are:")
for word in words:
print(word)
This works -
def str_sort(string):
b = string.split('-')
b.sort()
c = '-'.join(b)
return c
a = input('Enter a sequence of colors separated with hyphen: ')
str_sort(a)
This will solve your problem:
inputs = "green-red-yellow-black-white"
def sort_inputs(inputs):
inputs_list = inputs.split('-')
sorted_input = sorted(inputs_list)
final = "-".join(term for term in sorted_input)
return final
final = sort_inputs(inputs)
print(final)
