How to Avoid the TypeError: Input Expected at Most 1 Argument, Got 3 in Python

1. Take User Input in Python
2. Avoid the TypeError: input expected at most 1 argument, got 3 Error in Python

In Python programming, we have two built-in methods to take the user’s input: input(prompt) and raw_input(prompt). The second method, raw_input(prompt), is used in the older versions of Python like 2.X, and the input(prompt) is still in use.

This article will focus on the input(prompt) method.

Take User Input in Python

In Python, we will use the built-in input() function to take input from users and use it in the program accordingly.

Use of the input() function in Python:

name = input("Hey! What is your name? ")
print("Nice to meet you ", name)

Output:

Hey! What is your name? Zeeshan Afridi
Nice to meet you  Zeeshan Afridi

In the above program, we have used the input(prompt) function to ask the user’s name. As the user inputs their name, it will be stored in the name variable, which you can later utilize in your program anywhere needed.

Avoid the TypeError: input expected at most 1 argument, got 3 Error in Python

In computer programming, the TypeError is a syntactical error that means the developer has made some mistakes writing the program because of an invalid syntax of input or passing extra arguments to the functions. And one of the common errors is TypeError: input expected at most 1 argument, got 3.

Let’s understand it through an example:

name = input("Please enter your name: ")
age = input("Please enter your age: ")
print("Your good name is ", name, " and your age is ", age)

goal = input("What is your life goal Mr. ", name, " ?")
print(goal)
print("Awesome!")

Output:

Please enter your name: Zeeshan Afridi
Please enter your age: 24
Your good name is  Zeeshan Afridi  and your age is  24

TypeError: input expected at most 1 argument, got 3

In the above program, the first 3 lines are executed smoothly, but the next line of code goal = input("What is your life goal Mr. ", name, " ?") has thrown an error TypeError: input expected at most 1 argument, got 3.

This is because the Python input() function only expects a single argument, but we have passed three arguments to the input() function. The first argument is the string What is your life goal Mr. , the second argument is the variable name, and the last argument is again a string ?.

We have separated these arguments with the comma ,, which indicates that each is a separate argument. But, if you want to print the input prompt as it is, you have to concatenate these arguments to make it a single argument to meet the input() function’s expectation.

Let us understand it through an example:

name = input("Please enter your name: ")
age = input("Please enter your age: ")

print("\nYour good name is ", name, " and your age is ", age)

goal = input("What is your life goal Mr. " + name + " ? ")
print("Awesome!")

Output:

Please enter your name: Zeeshan Afridi
Please enter your age: 24

Your good name is  Zeeshan Afridi  and your age is  24
What is your life goal Mr. Zeeshan Afridi ? To be a Python Developer
Awesome!

In the above program, we have concatenated the argument of the input() function with the help of the plus symbol + to make them a single argument and to avoid the input TypeError.
