Strings are a collection of characters, and these characters can be accessed anytime by a program developer based on their position. This is known as indexing. Indexing is a technique in Python that is used to get back a one-character string at the specified position or offset. Now, in ca...

Converting a bytestring to a string To convert a bytestring back to a regular string, utilize the decode() method. This reverses the encoding process and is useful when you need to present or manipulate the data in a string format. Example In this example, we have a bytestring with the...
TypeError: %d format: a number is required, not str The % Operator as format specifiers in python We can also use the % operator to specify the format of numbers in the strings. As discussed above, we can insert a variable into a string using the % operator. In the case of integers...
A string is a data type used in programs to denote a sequence of characters. Strings can be used to represent names, addresses, documents, emails, and messages. Strings are available in practically every programming language. We will use Python to illustrate strings but similar notation is avail...
Prefix of 'u' with a string The prefix of'u'in a string denotes the value of type Unicode rather thanstring(str). However, the Unicode strings are no longer used in Python3. The prefix of'u'in a string denotes the value of type Unicode rather than str. However, the Unicode ...
