Python: Check whether all items of a list is equal to a given string

Python List: Exercise - 57 with Solution

Write a Python program to check if all items of a given list of strings is equal to a given string.

Python: Check whether all items of a list is equal to a given string

Sample Solution-1:

Python Code:

color1 = ["green", "orange", "black", "white"]
color2 = ["green", "green", "green", "green"]

print(all(c == 'blue' for c in color1))
print(all(c == 'green' for c in color2))

Sample Output:

False                                                                                                         
True

Sample Solution-2:

Checks if all elements in a list are equal:

Use set() to eliminate duplicate elements and then use len() to check if length is 1.

Python Code:

def all_equal(nums):
  return len(set(nums)) == 1
print(all_equal([1, 2, 3, 4, 5, 6]))
print(all_equal([4, 4, 4, 4, 4])) 

Sample Output:

False
True

Floor Division:

When we speak of division we normally mean (/) float division operator, this will give a precise result in float format with decimals.

For a rounded integer result there is (//) floor division operator in Python. Floor division will only give integer results that are round numbers.

print(1000 // 300)
print(1000 / 300)

Output:

3
3.3333333333333335
