Python TypeError: ‘list’ object is not callable

By: On:

In this Python tutorial, we will discuss how to fix “typeerror and attributeerror” in python. We will check how to fix the error called typeerror: ‘list’ object is not callable, also we will check typeerror: unsupported operand type(s) for +: ‘int’ and ‘str’ and python object has no attribute.

TypeError: ‘list’ object is not callable

In python, we get this error when we pass the argument inside the print statement, the code contains the round bracket to print each item in the list due to which we get this typeerror.


Example:

my_list = ["Kiyara", "Elon", "John", "Sujain"]
for value in range(len(my_list)):
print(my_list(value))

After writing the above code, Ones you will print “my_list(value)” then the error will appear as a “ TypeError: ‘list’ object is not callable  ”. Here, this error occurs because we are using the round bracket which is not correct for printing the items.

You can see the below screenshot for this typeerror in python

TypeError: 'list' object is not callable
TypeError: ‘list’ object is not callable

To solve this python typeerror we have to pass the argument inside the square brackets while printing the “value” because the list variable works in this way.


Example:

my_list = ["Kiyara", "Elon", "John", "Sujain"]
for value in range(len(my_list)):
print(my_list[value])

After writing the above code, Ones you will print “ my_list[value] ” then the output will appear as a “ Kiyara Elon John Sujain ”. Here, the error is resolved by giving square brackets while printing.

You can refer to the below screenshot how typeerror is resolved.

TypeError: unsupported operand type(s) for +: ‘int’ and ‘str’

We get unsupported operand type(s) for +: ‘int’ and ‘str’ error when we try to add an integer with string or vice versa as we cannot add a string to an integer.

Example:

a1 = 10
a2 = "5"
s = a1 + a2
print(s)

After writing the above code, Ones you will print “(s)” then the error will appear as a  TypeError: unsupported operand type(s) for +: ‘int’ and ‘str’  ”. Here, this error occurs because we are trying to add integer and string so it returns an error.

You can see the below screenshot typeerror: unsupported operand type(s) for +: ‘int’ and ‘str’ in python

TypeError: unsupported operand type(s) for +: 'int' and 'str'
TypeError: unsupported operand type(s) for +: ‘int’ and ‘str’

To solve this python typeerror we have to convert the string value to an integer using the int() method so, in this way we can avoid this error.

Example:

a1 = 10
a2 = "5"
s = a1 + int(a2
)
print(s)

After writing the above code, Ones you will print “ (s) ” then the output will appear as a “ 15 ”. Here, the error is resolved by converting the value of a2 to an integer type, and then it added two values.

You can refer to the below screenshot of how unsupported operand type(s) for +: ‘int’ and ‘str’ is resolved.

Python object has no attribute

In python, we get this attribute error because of invalid attribute reference or assignment.

Example:

a = 10
a.append(20)
print(a)

After writing the above code, Ones you will print “a” then the error will appear as an “ AttributeError: ‘int’ object has no attribute ‘append’ ”. Here, this error occurs because of invalid attribute reference is made and variable of integer type does not support append method.

You can see the below screenshot for attribute error

To solve this python attributeerror we have to give a variable of list type to support the append method in python, so it is important to give valid attributes to avoid this error.

Example:

roll = ['1','2','3','4']
roll.append('5')
print('Updated roll in list: ',roll)

After writing the above code, Ones you will print then the output will appear as an “Updated roll in list: [‘1’, ‘2’, ‘3’, ‘4’, ‘5’] ”. Here, the error is resolved by giving the valid attribute reference append on the list.

You can refer to the below screenshot how attributeerror is resolved.
