by

In this tutorial, we will explain to you the step by step process on how to solve the module ‘pexpect’ has no attribute ‘timeout’.

Why does this error occurs and what is pexpect in Python?

Why this error module ‘pexpect’ has no attribute ‘timeout’ occur?

This error occurs because the module ‘pexpect‘ doesn’t have an attribute called ‘timeout‘.

The most likely reason for this error is that you are using code that is written for an older version of the ‘pexpect‘ module.

Which had a ‘timeout‘ attribute, yet the newer version of the module doesn’t have it.

What is Pexpect in Python?

Pexpect is a Python module that provides a simple interface for controlling and automating other programs, such as SSH, Telnet, and FTP clients.

Pexpect is based on the Unix expect command, which allows users to interact with command-line programs by sending and receiving text-based responses.

This is very useful for automating tasks, testing applications, or interacting with remote systems.

Causes of Module ‘Pexpect’ Has No Attribute Timeout

  • Outdated Version of Pexpect Module
    • One of the most common causes of the AttributeError: module pexpect has no attribute timeout error is using an outdated version of the Pexpect module.
  • Wrong Import Statement
    • Another common cause of the AttributeError: module ‘pexpect’ has no attribute timeout error and is using the wrong import statement for the Pexpect module.

How to solve the attributeerror: module pexpect has no attribute timeout?

Solution 1: Upgrade Pexpect Module

If you are using an outdated version of the Pexpect module, you must upgrade to a latest version that includes the timeout attribute.

You can upgrade Pexpect using the pip package manager through running the following command:

pip install --upgrade pexpect

If you run the command it will download and install the latest version of Pexpect on your system.

pip install pexpect in attributeerror: module 'pexpect' has no attribute 'timeout'

Solution 2: Use the Correct Import Statement

If you are getting the AttributeError: module pexpect has no attribute timeout error through using the wrong import statement, you can solve it by using the correct import statement.

Instead of using the “from pexpect import *” statement, you should use the “import pexpect” statement and then access the timeout attribute using “pexpect.timeout“.

This is the following code to import:

import pexpect
child = pexpect.spawn('some_command')
child.timeout = 10

Solution 3: Define a Custom Timeout Attribute

If you are still encountering the error after upgrading Pexpect or using the correct import statement, you can define a custom timeout attribute for the Pexpect module.

This is an example:

import pexpect
class MySpawn(pexpect.spawn):
    def __init__(self, command, timeout=30, **kwargs):
        super(MySpawn, self).__init__(command, timeout=timeout, **kwargs)

In this example, we defined the custom class called “MySpawn” that extends the pexpect.spawn class.

The init() method of the MySpawn class sets the timeout attribute to 30 seconds by default, yet you can modify this value to any value that you want.
