TypeError: input expected at most 1 argument, got 3

TypeError: input expected at most 1 argument, got 3 #

The Python "TypeError: input expected at most 1 argument, got 3" occurs when we pass multiple arguments to the built-in input() function. To solve the error, use a formatted string literal to concatenate the arguments into a single string.

Here is an example of how the error occurs.

Copied!
w = 'name'

# ⛔️ TypeError: input expected at most 1 argument, got 3
s = input('Your ', w, ': ')

One way to solve the error is to use the addition (+) operator to concatenate the strings.

Copied!
w = 'name'

s = input('Your ' + w + ': ')

print(s)

The addition (+) operator can be used to concatenate strings.

Copied!
print('a' + 'b' + 'c')  # 👉️ 'abc'

An alternative approach is to use a formatted string literal.

Copied!
w = 'name'

s = input(f'Your {w}: ')

print(s)

Make sure to wrap expressions in curly braces - {expression}.

This solves the error because we are passing a single, string argument to the input() function.

The input function takes an optional prompt argument and writes it to standard output without a trailing newline.

Copied!
s = input('Your name: ')

print(s)

The function then reads the line from input, converts it to a string and returns the result.

An alternative to providing the prompt argument is to use calls to the print() function.

Copied!
print('Your name: ')

s = input()

print(s)

This is very similar to passing the prompt argument to the input() function but instead of showing the prompt on the same line, it is displayed on a separate line.

The Python "TypeError: input expected at most 1 argument, got 3" occurs when we pass multiple arguments to the built-in input() function. To solve the error, use a formatted string literal to concatenate the arguments into a single string.
