Python 2.7和Flask-使用venv时，使用“ Random”模块中的函数返回“ 500 Internal Server Error”

Question

I'm testing a web service written with python and flask. Within that service I want to generate a random number. None of the solutions posted on the web seem to work, as if the "random" module does not work. I checked, and there's no random.py or random.pyc within the folders around the webservice.py

Here's how I start the web service:

$ . venv/bin/activate
$ python webservice.py

How can I fix random module not being available when running in a virtual environment?

import random
from random import randint

x = random.random()*100
x = randint(0,10)
print 'r' + x #does not work 

Here's what's in the venv folder:

Answer 1

Check to see if the help("random") method will give a list.

• Then reinstall the module in that venv. Also what is in the lib folder?

Answer 2

Seems like you try to add string and integer.

Making a string out of a string and an integer in Python

print 'x' + str(randint(0,10)) # try casting the int to string :)
