How to Solve TypeError: ‘str’ object is not callable
This error occurs when you try to call a string as if it were a function. This error can occur if you override the built-in str() function or you try to access elements in a string using parentheses instead of square brackets. You can solve this error by ensuring you...
How to Solve Guide for Python AttributeError
We raise a Python AttributeError when we try to call or access an attribute of an object that does not exist for that object. This tutorial will go through what an attribute is, what the AttributeError is in detail, and we will go through four examples to learn how to...
What is the Ternary Operator in Python?
Conditional statements, such as if statements, direct the flow of programs by specifying particular blocks of code run only if a specific condition or set of conditions are met. We can test for a condition using the ternary operator. The ternary operator provides an...
How to Solve Python IndexError: single positional indexer is out-of-bounds
Indexing is an essential tool for storing and handling large and complex datasets with rows and columns. In Python, we use index values within square brackets to perform the indexing. If we try to access an index beyond the dimensions of the dataset, we will raise the...
How to Solve Python SyntaxError: ‘break’ outside loop
The break statement terminates the current loop and resumes execution at the next statement. You can only use a break statement inside a loop or an if statement. If you use a break statement outside of a loop, then you will raise the error "SyntaxError: 'break'...
How to Solve TypeError: ‘float’ object is not iterable
Floats and iterables are distinct objects In Python. A float is any decimal point number, and an iterable is an object capable of returning elements one at a time, for example, a list. A float is a single value and does not contain other values. If you try to iterate...
How to Solve Python SyntaxError: ‘return’ outside function
In Python, the return keyword ends the execution flow of a function and sends the result value to the main program. You must define the return statement inside the function where the code block ends. If you define the return statement outside the function block, you...
How to Solve Python TypeError: unhashable type: ‘dict’
In Python, a dictionary is stores data in key:value pairs. Python 3.7 dictionaries are ordered data collections; Python 3.6 and previous dictionaries are unordered. In a Python dictionary, all keys must be hashable. If you try to use the unhashable key type...
How to Solve Python TypeError: ‘function’ object is not subscriptable
In Python, a function is a block of code that only runs when called. You can pass data, known as parameters or arguments, to a function, and a function can return data as a result. To call a function, you must use the function name followed by parentheses () and pass...
How to Calculate the Square of a Number in Python
The square of a number results from multiplying a number by itself. The square of the number is the same as raising the number to the power of two. For example $latex 8 \times 8 = 64$, which is equal to $latex 8^{2}$ as well. The square of real numbers is always...
