I have the following exercise:
Two words are anagrams if you can rearrange the letters from one to spell the other.
Write a function called is_anagram that takes two strings and returns True if they are anagrams.
I have developed a function, but it is not working properly and I cannot find out why. Could anybody tell me what I am doing wrong? Thank you very much.
def isa(s,t):
if len(s)!=len(t):
print "impossible"
if len(s)==len(t):
i=0
while i<len(s)-1:
for i in s:
if i in t:
print "yay"
print "NO"
import collections
def is_anagram(s,t):
return collections.Counter(s) == collections.Counter(t)

I want to take words a user provides, store them in a list, and then modify those words so that every other letter is capitalized. I have working code but it is repetitive. I cannot for the life of me figure out how to get all the words ran through in one function and not have it output one long string with the spaces removed. Any help is appreciated.
This is my current code:
def sarcastic_caps(lis1):
list=[]
index=0
for ltr in lis1[0]:
if index % 2 == 0:
list.append(ltr.upper())
else:
list.append(ltr.lower())
index=index+1
return ''.join(list)
final_list.append(sarcastic_caps(lis1))
Imagine 4 more iterations of this ^. I would like to do it all in one function if possible?
I have tried expanding the list index but that returns all of the letters smashed together, not individual words. That is because of the .join but I need that to get all of the letters back together after running them through the .upper/.lower.
I am trying to go from ['hat', 'cat', 'fat'] to ['HaT', 'CaT', 'FaT'].
Each number call that contains a value (2,4,8) will output "Clap", if not "No clap"
Call
def clapping (number)
def clapping (772)
output:
"Clap"
I made the program, but it seems something is wrong. Can I ask for help to check which is wrong
import re
def clapping(number):
return "Clap" if re.findall("[248]+",number) else "No Clap"
print(clapping(779))
The regexp functions require a string to search, so you have to convert the number to a string with str(number).
There's also no need to use findall(). You only need to know if the regexp matches one time, you don't need a list of all the matches. Similarly, you don't need the + quantifier, since matching a single character is enough.
def clapping(number):
return "Clap" if re.search("[248]",str(number)) else "No Clap"
Very new to the world of programming and just starting to learn, working through Flatiron School prework and have been doing ok but unable to understand "if" and "else" statements for some reason. The problem is similiar to Chris Pine 'deaf grandma' problem but without saying "BYE!" three times.
~The method should take in a string argument containing a phrase and check to see if the phrase is written in all uppercase: if it isn't, then grandma can't hear you. She should then respond with (return) HUH?! SPEAK UP, SONNY!.
~However, if you shout at her (i.e. call the method with a string argument containing a phrase that is all uppercase, then she can hear you (or at least she thinks that she can) and should respond with (return) NO, NOT SINCE 1938!
I have so far:
def speak_to_grandma
puts "Hi Nana, how are you?".upcase
if false
puts "HUH?! SPEAK UP, SONNY!"
else
puts "NO, NOT SINCE 1938!"
end
end
but am getting wrong number of arguments...how am I supposed to add argument while using the if/else statements? This is probably a very easy and basic question but can't seem to get my head around this (overthinking probably).
Any help and clarity would be greatly appreciated.
input_phrase = "Hi Nana, how are you?"
def speak_to_grandma(phrase)
# Check if string equals same phrase all upper case letters, which means string is all uppercase
if phrase == phrase.upcase
# return this string if condition is true
puts "NO, NOT SINCE 1938!"
else
# return this string if condition is false
puts "HUH?! SPEAK UP, SONNY!"
end
end
# execute function passing input_phrase variable as argument
speak_to_grandma(input_phrase)
how am I supposed to add argument while using the if/else statements?
This is probably a very easy and basic question but can't seem to get
my head around this (overthinking probably).
Your mistake was that function was not accepting any arguments, here it accepts "phrase" variable as argument and processes it:
def speak_to_grandma(phrase)
You had
if false
but did not check what exactly is false.. To rewrite my version with "false" :
input_phrase = "Hi Nana, how are you?"
def speak_to_grandma(phrase)
# Check if it is false that string is all upper case
if (phrase == phrase.upcase) == false
# return this string if condition is false
puts "HUH?! SPEAK UP, SONNY!"
else
# return this string if condition is true
puts "NO, NOT SINCE 1938!"
end
end
speak_to_grandma(input_phrase)
Here I am evaluating
if (phrase == phrase.upcase) == false
Basically means "if expression that phrase equals phrase all uppercase is false"
Im taking an online beginner course through google on python 2, and I cannot figure out the answer to one of the questions. Here it is and thanks in advance for your help!
# A. match_ends
# Given a list of strings, return the count of the number of
# strings where the string length is 2 or more and the first
# and last chars of the string are the same.
# Note: python does not have a ++ operator, but += works.
def match_ends(words):
a = []
for b in words:
retun
I tried a few different things. This is just where i left off on my last attempt, and decided to ask for help. I have spent more time thinking about this than i care to mention
You should go through the course materials carefully. This can be solved easily if you have a beginner level understanding of Python. See the following code snippet:
def match_ends(words):
count = 0
for word in words:
if len(word) >= 2 and word[0] == word[-1]:
count += 1
return count
I am trying to write a code that will scramble the words in a sentence and return a string that is in a different order
from random import shuffle
def scramble():
a=len("this is a sentence")
for i in range(a):
random.shuffle("this is a sentence")
print(random.shuffle)
Not sure if I am even on the right track, however I believe the loop might be the issue
random.shuffle works on a a sequence, not a string. So first, use str.split to split the sentence into a list of words, call shuffle that, then turn it into a string again using str.join:
from random import shuffle
def scramble(sentence):
split = sentence.split() # Split the string into a list of words
shuffle(split) # This shuffles the list in-place.
return ' '.join(split) # Turn the list back into a string
print scramble("this is a sentence")
Output:
sentence a this is
