len library python code example

Example 1: len python

mystring = 'Hello'
#Counts the amount of letters in the string
len(mystring)	# = 5	

#Can also count the number of items in a list
mylist = ['Hello', 'Goodbye', 'Morning']
len(mylist)		# = 3

Example 2: python3 any

# True since 1,3 and 4 (at least one) is true
l = [1, 3, 4, 0]
print(any(l))

# False since both are False
l = [0, False]
print(any(l))

# True since 5 is true
l = [0, False, 5]
print(any(l))

# False since iterable is empty
l = []
print(any(l))
