Question
Write the code in python to define a function has_repeat(mystr), which takes a string parameter and returns a boolean result.
- If mystr has a character that is repeated (count is more than 1 for that character), return True
- Otherwise, return False
Hint: You can solve this problem by iterating over the characters in mystr and comparing each character's count with 1.
For example:
Test | Result |
---|---|
print(has_repeat("Happy")) | True |
print(has_repeat("sad")) | False |
print(has_repeat("salmons")) | True |
print(has_repeat("Trouts")) | False |

- Write a function that counts and returns the number of vowels in a word. The function's one parameter is a constant string reference The function returns the number of vowels in the string parameter as an int A word is a collection of letters of the alphabet. The normal vowels are the letters, ignoring case, A, E, I, O, U If a word does not contain any normal vowels, then, ignoring case, Y is a vowel. for example "yellow" contains two normal vowels, "o" and "w" "pygmy" contains no normal vowels but contain two vowels, two occurrences of "y" "psst" contains neither normal vowels nor "y"s "y" is not a vowel in "yellow" but "y" is a vowel in "pygmy" Create a text file of words, one word per line Apply the function to each word in the file The program displays each word and its vowel count on its own line For example, john 1 threw 1 the 1 orange 3 into 2 the 1 sky 1 ---------------------------------------------------------------------------------------------------------- Criteria 1)…arrow_forwardWrite a function that takes an integer.

- Write the function that takes three dimensions of a brick: height(a), width(b) and depth(c) and returns true if this brick can fit into a hole with the width (w) and height(h).

- In Phython Language: The DNA of a living organism consists of a string of 4 different bases represented with letters A, T, G, C. The DNA has a double helix structure which means these bases are paired in the string. An A base is always paired with a T base molecule and a C base is always paired with G molecule. Write a function matchingPair that accepts a single strand of the DNA structure as a string parameter and produces the pairing strand as a result and returns it. Strings can be considered as list of characters. Therefore the subscript notation that we use for lists is acceptable for strings as well. For example to reach to the 4th character of a string variable mystring, you may use the notation mystring[3]. Write another function search that accepts a long and a short DNA strand as parameters. The function should return the index positions of the occurrences of the short strand in the long strand as a list. Test your functions by accepting a long strand of DNA to find the…arrow_forwardI am trying to create a monthly mortgage calculator in C++, but i cannot get the function I am trying to create to work.

Then converts this string using the following three rules and finally RETURNS a new string to the function call. If the string is one character long, leave it alone. If the string ends with a vowel (a, e, i, o, u), just add ‘yay’ to the beginning of the string. (e.g., “apple” => “yayapple”) Otherwise, the last letter of the string is moved to the front and ‘ay’ is appended to the end (e.g., “dalek” => “kdaleay”) Assume, the argument string will always be in lowercase letters without any spaces.
