Module import fails for unknow reason-CodePudding

Today I tried to make a project where I need to use import random, but when I use it, its imports not library but only function random, and I get alert: NameError: name 'randint' is not defined.

My code looks like:

import random

randomList = []

def randoming() :
    for i in range(8) :
        randomNum = randint(2, 8)
        randomList.append(randomNum)


randoming()

def sixCounter() :
    sixNums = 0
    for a in range(8) :
        if randomList[a] == 6 :
            sixNums = sixNums   1
    print(f"In that list are {sixNums} six numbers")


print("The numbers in list are:")
print(*randomList, sep = ", ")
sixCounter()

You either need to reference randint as random.randin or import randint from random

i.e. either:

from random import randint

randomList = []

def randoming() :
    for i in range(8) :
        randomNum = randint(2, 8)
        randomList.append(randomNum)


randoming()

def sixCounter() :
    sixNums = 0
    for a in range(8) :
        if randomList[a] == 6 :
            sixNums = sixNums   1
    print(f"In that list are {sixNums} six numbers")


print("The numbers in list are:")
print(*randomList, sep = ", ")
sixCounter()

import random

randomList = []

def randoming() :
    for i in range(8) :
        randomNum = random.randint(2, 8)
        randomList.append(randomNum)


randoming()

def sixCounter() :
    sixNums = 0
    for a in range(8) :
        if randomList[a] == 6 :
            sixNums = sixNums   1
    print(f"In that list are {sixNums} six numbers")


print("The numbers in list are:")
print(*randomList, sep = ", ")
sixCounter()

THE PROBLEM
When you import any module as following,

import module

to call any function from the module, you have to do it as an attribute of the module. Like this:

module.function()

Calling only the function will raise an undefinition error.

THE SOLUTION
To solve your problem, call the randint function like this:

random.randint()

OR import the module like this

from random import *

This instruction will "move" all the functions of the module random to your code, so that you don't have to call any function as an attribute of the module.
