Hello!

I am grabbing a some data off of an API. I then am trying to take the variable in which I have stored the gathered data and write it to a text file.

When I define the type my variable is it shows

<class '_io.TextIOWrapper'>

I have tried to figure out how to convert it to a string (as that what the error yells at me for) but I cannot find the function.

import time, json, requests

def btstamp():
    bitStampTick = requests.get('https://www.bitstamp.net/api/ticker/')
    return bitStampTick.json()['last']

bitstampprice = (btstamp())

print (bitstampprice)	

bitstampprice = open("testwrite1.txt", "w+")

print (type(bitstampprice))

bitstampprice.write(bitstampprice)

bitstampprice.close()

Here is the error

C:\TradingBot>export.py
6456.95
<class '_io.TextIOWrapper'>
Traceback (most recent call last):
  File "C:\TradingBot\export.py", line 15, in <module>
    bitstampprice.write(bitstampprice)
TypeError: write() argument must be str, not _io.TextIOWrapper

C:\TradingBot>

I have spent a good amount of time doing this and its getting late. Any help would be greatly appreciated.

I go into some info about _io.TextIOWrapper and the info is a bit advance for me.

Why is my data being returned in this type?

How come it is not a integer as it is shown when I "print" the variable?

Thanks

Hello everyone, for the purpose of my project I need to convert a string (an email) to io.TextIOWrapper format so I can send the email. Does anyone know how I can convert? Thank you

I am writing function to help me printing data in text files with different types. in my code for function def write(self, file:io.TextIOWrapper): i want to specify type of my file variable to improve my documentation and code readability. Any idea how to do this?

class Node:
    Id: int
    X: float
    Y: float
    Z: float

    def __init__(self, Id: int, x: float, y: float, z: float):
        self.Id = int(Id)
        self.X = float(x)
        self.Y = float(y)
        self.Z = float(z)

    def write(self, file:io.TextIOWrapper):
        file.write(f"{self.Id},{self.X:0.4f},{self.Y:0.4f},{self.Z:0.4f};\n")

    def __str__(self):
        return f"{self.Id}:{self.X},{self.Y},{self.Z}"

I'm supposed to create a dictionary from the values in a file and search for 'Polly' and remove it if it's in the file,

I kept getting errors so I'm just trying to get it to print the value just so I can see what I'm doing wrong and even at the most simple level I keep getting errors,

I'm in my first semester so this is all still new to me

employees = {}
employees = open('dictionary_values.txt', 'r')
print(employees['Polly'])

Traceback (most recent call last):
  File "main.py", line 3, in <module>
    print(employees['Polly'])
TypeError: '_io.TextIOWrapper' object is not subscriptable
