Understand the term 'predefined function'
Identify and use appropriate predefined functions
At National 5 you looked at the following predefined function:
Random
Round
Length
The random predefined function generates a random number between a range in Python:
import random
#Generates a number between 10 and 100
print(random.randint(10, 100))The round function rounds a number to a specified number of decimal places.
x = 3.145
#Will give us 3.15
print(round(x, 2))
#Will give us 3.0
print(round(x, 0))The length function is used to calculate the length of an array.
fib = [1, 2, 3, 5, 8, 13, 21, 34, 55, 89]
#Should print 10
print (len(fib))The lower and upper functions turn a string to lowercase or uppercase.
x = "John"
y = x.lower()
z = x.upper()
print(y)
print(z)In your jotter, write down an example of how each of the predefined function shown before could be used in Python
