Check if each number is prime in the said list of numbers: False Flowchart: Sample Solution-2: Python Code: # Define a function named 'test' that takes two inputs: 'text' (a string) and 'n' (an integer).deftest(text,n):# Use a list comprehension to create a list 't' containing...
Check if the input is a number using int() or float() in Python Theint()orfloat()method is used to convert any input string to a number. We can use this function to check if the user input is a valid number. If the user input is successfully converted to a number usingint()orfl...
Suppose we have a number n. We have to check whether n is Euclid number or not. As we know Euclid numbers are integer which can be represented as n= Pn+1 where is product of first n prime numbers. So, if the input is like n = 211, then the output will be True n can be ...
The count() method in Python provides a direct way to check if an element exists in a list by returning the number of times the element appears. This method is particularly useful when not only the presence but also the frequency of an element is of interest. It operates by scanning the...

print(is_even(31)) Output: True False I have executed the above example code and added the screenshot below. In this code, theis_evenfunction takes a number as input and uses the modulo operator to check if it is divisible by 2. If the remainder is 0, the function returnsTrueindicatin...
You can simply check if the List is empty with: ifnotmy_list:print("List is empty") This is using theTruth Value Testingin Python, also known as implicit booleaness or truthy/falsy value testing. Among other rules it defines that empty sequences and collections like'', (), [], {},...
You can check if a variable is an integer using the type() function, passing the variable as an argument, and then comparing the result to the int class:age = 1 type(age) == int #TrueOr using isinstance(), passing 2 arguments: the variable, and the int class:...
