How to Manage Python Packages with PIP
Practical guide on how to manage the Python Packages with PIP by upgrading the existing packages, installing specific versions of Python packages, and so on.
How to Rename File in Python
In Python, the os.rename() function is utilized to change the names of both files and directories. Using this function, we can also change the file extension.
How to Get a Position of Element in Python?
In Python, various functions/methods, such as the “index()”, and “find()” methods are used for getting the exact position of an element.
Seaborn Catplot
In Python, the “seaborn.catplot()” method of the “seaborn” module is used to create a variety of categorical plots, including strip plots, swarm plots, etc.
Pandas Add Index
To add an index to the Pandas DataFrame, the “dataframe.set_index()” method or the “dataframe.index()” attribute is used in Python.
Pandas Get Most Frequent Value
To get the most frequent value in pandas, use the panda series “mod()” method or the “value_counts()” method followed by “idxmax()” method.
Scipy Tplquad
The “scipy.integrate.tplquad()” method is used to perform triple integration of simple to complex functions over a range of variables in Python.
Pandas Add Row to DataFrame
To add/insert a row to Pandas DataFrame, the “dataframe.loc”, “pandas.concat()”, and “dataframe.append()” function is used in Python.
Python bytearray example
In Python, the inbuilt “bytearray()” method is utilized to retrieve a bytearray object which is an array of specified bytes.
How Python Functions Remove Characters From A String
The “replace()” method, “translate()” method, “re.sub()” method, and the “for” loop is used to remove/delete the characters from the input string.
Python List Length
The “len()” function, “for” loop, and the “length_hint()” method are utilized in Python to determine/get the length of the list.
Python File Seek
The “file.seek()” method is utilized in Python to move or change the position of the file handle pointer according to the specified offset value.
Python random string generation
The “random.choices()” method of the random “module” and the “secrets.choice()” method of the “secrets” module is used to retrieve the random string in Python.
Python dict setdefault
The “setdefault()” method retrieves the dictionary key value that is present in the dictionary or inserts a key with a default value if the key is not present.
Python Print Dict Keys
The “dict.keys()” method, “dictionary.items()” method, “List Comprehension” and “itemgetter()” function is used to print dictionary keys in Python.
Python hash() Method
In Python, the “hash()” function takes the hashable object such as str, int, float, etc. as an argument and retrieves the integer type hash value.
Python Randomly Select From List
The “random.choice()”, “random.randrange()”, “random.sample()”, and “random.shuffle()” methods are used to randomly select an item from the list in Python.
Python Flatten List of Lists
The “List Comprehension”, “itertools” module, “reduce()” function, “sum()” function, and nested “for” loops are used to flatten a list of lists.
Python Data Types
In Python programming language, the “Data Types” indicate what type of data can be stored or assigned to the specified variables.
Python infinity representation
The “math.inf”, “np.inf”, “float()” function, and “decimal” modules are utilized to represent positive and negative infinity values in Python.
