Python Forum

I am new to programming -- just doing simple hand-on and input function is not working in VS Code (Anaconda). just tried same thing in Juptyr notebook and it responds as expected.
1st Code with issues
replicating part of code:

import sys
print ("enter your name ")
x= input ()
print ("hello  ", x)

## This is asking for input and printing correct result in Jupyter notebook--
while same is giving no results in VS code - below is the snippet I get in output terminal after I execute these statement:

Output:
enter your name
>>> x= input ()
print ("hello  ", x)

## It is not asking me to enter the name##

2nd Code with issues

r = int (input ("enter a number"))
print (r*2)

giving correct output in Jupyter
while same is throwing error in VS Code:

r = int (input ("enter a number"))
print (r**2)

Error:
Error:
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: 'print (r**2)'
>>>

Please support to resolve, TIA!

In setting search code-runner.runInTerminal set to True.
More tips here VS Code from start,i to do also mention this in tutorial.

sorry couldn't find this code-runner.runInTerminal . I tried in File --> prefrences--> setting __> search.. but this flag code-runner.runInTerminal is not available

Yes i forget to mention that's a feature of Code Runner.
You should install it,also get a button for running code.
Also look a tutorial and set in code-runner.executorMap:

"python": "$pythonPath $fullFileName",

This make it always follow current Python interpreter,that's active down in left corner.

I have done as suggested

{
"files.autoSave": "afterDelay",
"python.dataScience.sendSelectionToInteractiveWindow": true,
"python.pythonPath": "C:\\ProgramData\\Anaconda3",
"code-runner.runInTerminal": true
}


after that-- just compiled below simple code and getting the below results again.. it is publishing 'none'.. while it has not asked any value from me

x = print("enter something")
print (x)

Error:
>>> x = print("enter something")
enter something
>>> print (x)
None

See this -- providing error.. not sure what is happening.

x = int(print("enter some nmberu"))
print (x)

Error:
>>> x = int(print("enter some nmberu"))
enter some nmberu
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'
>>> print (x)
None

print isn't used for reading input - it just prints the value and returns None. Why aren't you using input?!

You need to use input() rather than print().

x = int(input("enter some nmberu"))
print (x)

Output:
enter some nmberu5

No you have not
They change as was talking about was in code-runner.executorMap as in my tutorial.
Also between perl and php.

"php": "php",
"python": "$pythonPath $fullFileName",
"perl": "perl",

As mention now in last code use use print().
Your first code was:

r = int(input("enter a number: "))
print(r**2)

I can use Anaconda as demo as you use,the point now is that now if change Python interpreter,
all running of code will use that Python interpreter(down in left corner).


So now running code as a script an can type input in Terminal,
In interact interpreter it will be like this(enter after each line).

λ ptpython
>>> r = int(input("enter a number: "))
enter a number: 55
>>> r**2
3025

I use ptpython,but you can use eg IPython or JupyterLab which is the Browser version with a lot of features.
You just have to find a setup that work for you,as all of this can be confusing in the start.
