Parameter description:
- start-- Required, an integer, specifies the start value (inclusive), i.e., the generated random integer can take this value.
- stop-- Required, an integer, specifies the end value (inclusive), i.e., the generated random integer can take this value.

import random
# Generate a random integer between 1 and 10
random_number = random.randint(1, 10)
print(random_number)
import random
# Generate a random integer between 1 and 10
random_number = random.randint(1, 10)
print(random_number)
Output result:
8
In the above example,random.randint(1, 10)will generate a random integer between 1 and 10 (including 1 and 10), and assign it to the variable random_number.
Each time you run this code, you will get a different random integer.
Notes:
