Error: login() takes 1 positional argument but 2 were given
This error message is a Python exception that occurs when a function called login() is given more arguments than it expects.
The login() function is defined with only one parameter, but when calling the function, you provide two arguments.
Example 1:
Consider the following code:
def login(user):
print("Logging in as", user)
# Correct usage of the login() function
login("John") # only one argument provided, no error
In this example, the login() function expects one argument, which is the “user”. When calling the function with a single argument “John”, it will execute without any errors.
Example 2:
Now let’s consider a scenario where this error occurs:
def login(user):
print("Logging in as", user)
# Incorrect usage of the login() function
login("John", "password") # two arguments provided, causes an error
In this case, the login() function expects only one argument, which is the “user”. However, when calling the function with two arguments “John” and “password”, it causes the error because the function is provided with more arguments than it can handle.
To fix this error, make sure to adjust the number of arguments you pass to the login() function to match its definition.
