What is (File “”, line 1) in Python Programming

Share This Post

If you are still trying to learn Python then you may come to face some problems in coding. If you are still learning the Python programming language then you may have the complaint of some errors like a syntax error.

(File “<stdin>”, line 1) in Python

When you are using Python, File “”, line 1 refers to a code or statement in line 1 which is a type of error message. There doesn’t need to always be a File “”, line 1.

It can also be a File “”, line 2, File “”, line 3, File “”, line 4, etc. according to the line in which the error is present.

Whenever \ you enter an invalid syntax key or enter the wrong code on the interpreter, and then it will lead to a syntax error.

This error may arise due to the wrong use of function, command, or arrows.

For example

while True print('Hello world!')
File "", line 1
while True print('Hello world!')

Syntax Error: invalid syntax

In this example, Python is showing the line having an error as invalid syntax. The little arrows before the first line are pointing towards the line where the error is detected.

So, in this example, the error is at the function print (). A colon (:) is missing after the while true statement and before the print () function. In syntax error.

The name of the file and the line number is also printed so we can look into the case where an error arises.
The error may arise when we try to execute it even when the code is syntactically correct.

The errors that appear during the execution of codes are called exceptions. Executions are not easy to handle and result in errors in the message. In the code given below, the last line is showing the reason for error.

3 types of errors (File “<stdin>”, line 1) in Python

There are 3 types of errors mentioned (1) zero division error, (2) name error, (3) and type error.

Here the exceptions are occurring in the form of “Trackback”.

10 * (1/0)
Traceback (most recent call last):
File "", line 1, in Zero Division Error: division by zero>>> 4 + spam*3
Traceback (most recent call last):
File "", line 1, in Name Error: name 'spam' is not defined>>> '2' + 2
Traceback (most recent call last):
File "", line 1, in

Type Error: Can't convert 'int' object to str implicitly
In a syntax error, if you try to run Python file using a python interpreter.
You cannot use the interpreter in this type of files.

python test.py
File "", line 1

python wholeblogs.py

Syntax Error: invalid syntax

It shows that as we add an invalid code in line 1, it shows us an invalid syntax. Similarly, if we add the wrong data in the name file then it will show a name error.

For example,

>>> display
Traceback (most recent call last):
File "", line 1, in

Name Error: name ‘display‘ is not defined

Here we have entered the wrong code and the name is not displayed.

>>> display something
File "", line 1

Display something

Syntax Error: invalid syntax

This coding is showing a syntax error in line 1.

>>> open my file
File "", line 1

open my file

Syntax Error: invalid syntax

If we enter 1/0, it throws Zero Division Error in which the value is divided by zero even if it is not required.

>>> 1/0

Traceback (most recent call last):

File “”, line 1, in

Zero Division Error: Division by zero

So in the term line, 1 is used as it shows the error in line 1. If the error is in line 2 then there will be “line 2” written in the end.
