Iterating over rows in a DataFrame is a common operation when working with data, especially when you need to apply a function to each row or manipulate the data in some way. In this blog post, we will discuss different methods to iterate over rows in a DataFrame in Pandas,
How do I list all files of a directory in Python?
As a Python developer, you may come across a situation where you need to list all the files in a directory. Whether you want to loop through all files in a directory or simply display a list of files in a directory, Python provides an easy way to accomplish this
How to Find the Index of an Item in a List in Python
Lists are one of the most commonly used data structures in Python, and they provide a way to store collections of items that can be accessed and manipulated easily. Often, when working with lists, you’ll need to find the index of a particular item within the list. In this blog
How to Iterate Over Dictionaries Using ‘For’ Loops in Python
In Python, dictionaries are a commonly used data structure for storing and organizing data in key-value pairs. To work with these dictionaries, it’s often necessary to iterate over them and extract the data they contain. In this blog post, we’ve explored the various ways to iterate over dictionaries using ‘for’
How to Check if a File Exists Without Exceptions in Python
In this blog post, we explore how to check if a file exists without exceptions in Python. We first introduce the os module, which provides various functionalities for interacting with the operating system. Then, we dive into the os.path.isfile() method, which can be used to check for the existence of
TypeError: can’t multiply sequence by non-int of type ‘float’
The TypeError: can’t multiply sequence by non-int of type ‘float’ is due to the multiplication operator is used between a string and a float number in python. The string can’t multiply sequence by non-int of type float. The multiply sequence is created between a string and an integer value in
AttributeError: ‘dict’ object has no attribute ‘append’
The python AttributeError: ‘dict’ object has no attribute ‘append’ error happens when the append() attribute is called in the dict object. The dict object does not support the attribute append(). The elements can be added by assignment operator in dict. If the append() function is called in the ‘dict’, the
AttributeError: ‘NoneType’ object has no attribute ‘append’
The AttributeError: ‘NoneType’ object has no attribute ‘append’ error happens when the append() attribute is called in the None type object. The NoneType object has no attribute like append(). That’s where the error AttributeError: ‘NoneType’ object has no attribute ‘append’ has happened. The python variables, which have no value initialised,
TypeError: unsupported operand type(s) for +: ‘NoneType’ and ‘int’
In python, TypeError: unsupported operand type(s) for +: ‘NoneType’ and ‘int’ error occurs when an integer value is added to a variable that is None. You can add an integer number with a another number. You can’t add a number to None. The Error TypeError: unsupported operand type(s) for +:
TypeError: unsupported operand type(s) for -: ‘str’ and ‘str’
The python error TypeError: unsupported operand type(s) for -: ‘str’ and ‘str’ occurs when you try to subtract a string from another that contains numbers in both strings. The TypeError is due to the operand type minus (‘-‘) is unsupported between str (string). Auto casting is not supported by python.
TypeError: unsupported operand type(s) for -: ‘str’ and ‘int’
The TypeError: unsupported operand type(s) for -: ‘str’ and ‘int’ error occurs when an integer is subtracted from a string in python. Auto casting is not possible in python. You can subtract a number from another number. If you attempt to subtract an integer value from a string containing a
ValueError: invalid literal for long() with base 10:
The python error ValueError: Invalid literal for long() with base 10: occurs when the built-in long() function is called with a string argument which cannot be parsed as a long. The int() function returns a long object created from a string or number. If there are no arguments, it returns
ValueError: invalid literal for int() with base 16:
The python error ValueError: Invalid literal for int with base 16: occurs when the built-in int(val, 16) function is called with a string argument which cannot be parsed as a hexa decimal number. The int(val, 16) function returns an integer object created from a string or a hexa decimal number.
ValueError: invalid literal for float():
The python error ValueError: invalid literal for float(): occurs when the built-in float() function is called with a string argument which cannot be parsed as a float number. The float() function returns an float object created from a string or a decimal number. If there are no arguments, it returns
TypeError: ‘float’ object does not support item assignment
The python error TypeError: ‘float’ object does not support item assignment occurs when a value is inserted or changed in a float variable using an index by the assignment operator. The float variable is an immutable value. The float value can not be accessed using the index. If you attempt
