. def isPrime(N): i = 2 while i**2 <= N: if N % i == 0: return False i+=1 return True for i in range(3, 21 + 1): if isPrime(i): print(i, ‘is prime’) else: print(i, ‘is not a prime number’) First of all, create a function for determining whether or not a given number is … Read more
Assuming the content is in file “txt”, following code should work in python. (though it does not preserve the whitespaces) with open (“txt”) as f: for line in sorted( [line.rstrip().split() for line in f], key=lambda x : int(x[1]) ): print(” “.join(line)) Simply, in cmdline you can do something like below, while preserving white spaces sort … Read more

That is reinventing the wheel, use str.isalpha You could use assert and AssertionError from string import ascii_letters value = None while True: try: value = input(“Give a value: “) assert all(c in ascii_letters for c in value) break except AssertionError: print(“Invalid input, try again”) print(“Valid input:”, value) Give a value: aa! Invalid input, try again … Read more
You can use the ctypes module to do the conversion for you: sint32 = ctypes.c_int(uint24 + (byte << 24)).value This will give you a 32-bit signed integer. solved Converting uint24 and unsigned char to 32bit signed int with python struct
Use line.count(‘AA’) to count succeeding characters according to the rules you gave. 9 solved python code for counting characters from sequence file
What is length? length does not exist, but Node.length does. The reason return(1+length(self.next)) doesn’t work is because you’re calling length(), not Node.length(). Instead, try this: return(1+LinkedList.length(self.next)) Or this (my preference): return(1+self.next.length()) solved Why isn’t length(self.next) a valid expression in python? [closed]
You could try: y = re.findall(r”\(\s*[a-zA-Z]+\s*\)”, x) Where x is the input. Note – You will have to import re by using the statement import re before the program, to use the regex functions Explanation – re.findall is a module that returns an array of the matches found by the regex. The arguments are as … Read more
