How to Solve Python TypeError: ‘tuple’ object is not callable
If you try to call a tuple object, you will raise the error "TypeError: 'tuple' object is not callable". We use parentheses to define tuples, but if you define multiple tuples without separating them with commas, Python will interpret this as attempting to call a...
What is 12 Degrees Celsius in Fahrenheit?
We can measure temperature using two units: Celsius and Fahrenheit. We can convert temperature from degrees Celsius to degrees Fahrenheit using a formula. 12 degrees Celsius is equal to 53.6 degrees Fahrenheit. This tutorial will go through how to convert between the...
How to Solve Python ValueError: could not convert string to float
In Python, we can only convert specific string values to float. If we try to convert an invalid string to a float, we will raise the ValueError: could not convert string to float. To solve this error, ensure you strip the string of invalid characters like commas,...
How to Solve Python ValueError: I/O operation on closed file
If you try to access a closed file, you will raise the ValueError: I/O operation on closed file. I/O means Input/Output and refers to the read and write operations in Python. To solve this error, ensure you put all writing operations before closing the file. This...
How to Do Bubble Sort in Python
Bubble sort is a popular sorting algorithm that compares the adjacent elements in a list and swaps them if they are not in the specified order. This tutorial will go through how to implement the bubble sort algorithm in Python with the help of code examples. Got some...
How to Solve Python TypeError: unhashable type ‘set’
The error TypeError: unhashable type: ‘set’ occurs when trying to get a hash of a set object. For example, using a set as a key in a dictionary. To solve this error, we can cast the set to a frozenset or a tuple, which are both hashable container objects. This...
How to Solve Python TypeError: unhashable type: ‘numpy.ndarray’
The error TypeError: unhashable type: ‘numpy.ndarray’ occurs when trying to get a hash of a NumPy ndarray. For example, using an ndarray as a key in a Python dictionary because you can only use hashable data types as a key. We can use the update() method to...
How to Solve Python TypeError: unhashable type: ‘list’
The error TypeError: unhashable type: 'list' occurs when trying to get a hash of a list. For example, using a list as a key in a Python dictionary will throw the TypeError because you can only use hashable data types as a key. To solve this error, you can cast the...
How to Solve Python AttributeError: ‘list’ object has no attribute ‘shape’
In Python, the list data structure stores elements in sequential order. The numpy.shape() function gives us the number of elements in each dimension of an array. We cannot use the shape function on a list. If we try to use the numpy.shape() function on a list, you...
How to Solve Python AttributeError: ‘list’ object has no attribute ‘lower’
In Python, the list data structure stores elements in sequential order. We can use the String lower() method to get a string with all lowercase characters. However, we cannot apply the lower() function to a list. If you try to use the lower() method on a list, you...
