I am trying to send random data to API using python flask with intervals of 1 second. But it only shows the last array of data. I am using the following code:
import time
import random
import datetime
from flask import Flask
mylist = []
ct = datetime.datetime.now()
app = Flask(__name__)
@app.route('/')
def index():
mylist = []
ct = datetime.datetime.now()
for i in range(0, 61):
x = random.randint(1, 100)
mylist.append(x)
if len(mylist) == 11:
right_in_left_out = mylist.pop(0)
else:
right_in_left_out = None
time.sleep(1)
print(mylist)
return mylist
if __name__ == "__main__":
app.run(debug=True)
OUTPUT:
WARNING: This is a development server. Do not use it in a production deployment. Use a production WSGI server instead. * Running on
I am looking to send data the same way as it is being displayed in the IDE with 1 sec intervals.

The problem lies here
if len(mylist) == 11:
right_in_left_out = mylist.pop(0)
Once this code executes for the first time, your list size is back to 10 , further iterations everytime it becomes 11 and then back to 10!
CodePudding user response:
Your code is returning a list, and that is logical. If you want to return all the lists like the ones you displayed, you have to store them in a list of lists. I mean by that:
all_lists = []
mylist = []
ct = datetime.datetime.now()
for i in range(0, 61):
x = random.randint(1, 100)
mylist.append(x)
if len(mylist) == 11:
right_in_left_out = mylist.pop(0)
all_lists.append(mylist)
else:
right_in_left_out = None
time.sleep(1)
print(mylist)
return all_lists
There is also no need to use right_in_left_out
variable in your code.
