Python3 generates random number instances and python3 random number instances

This example describes how to generate a random number using python3. Share it with you for your reference. The specific implementation method is as follows:

This example is based on a small random number program seen in a book. After modification, it is changed to a number-guessing game and is now rewritten under python3.

This is a guess program in the console. winxp + python3.2 + eric5 and IDLE passed the test, but there is a problem with running the command line of winxp. The reason is unknown. Ubuntu + python3.1 passed the test.

The specific implementation code is as follows:

Copy codeThe Code is as follows: #-*-coding: UTF-8 -*-

How to Use python to generate a list composed of random numbers?

Need to use the random Module
Import random
N = random. randint (1, 10)
A random integer ranging from 1 to 10 is generated.
Insert list
[]. Append (n)
That's all. You can create a loop. For example, keep inserting the for loop.

Use python to randomly generate three arrays with ten elements and combine the three into an array. Pick out the odd and even numbers which are not repeated.

Def test ():
MinNum = 0 # random number start

# Three sequences are randomly generated and are integers.
List1 = [random. randint (minNum, maxNum) for I in xrange (10)]
List2 = [random. randint (minNum, maxNum) for I in xrange (10)]
List3 = [random. randint (minNum, maxNum) for I in xrange (10)]
LastList = list1 + list2 + list3 # combine
LastList = list (set (lastList) # remove duplicates. The set is unordered and not repeated.

OddNumList = [] # used to save the odd Sequence
EvenNumList = [] # used to save even numbers

For num in lastList:
If num % 2 = 0:
EvenNumList. append (num)
Else:
OddNumList. append (num)
Print u ":", oddNumList, "% d" % len (oddNumList)
Print u "even number:", evenNumList, "% d total" % len (evenNumList)
