python - Converting integer to string? - Stack Overflow

For Python 3.6 you can use the f-strings new feature to convert to string and it's faster compared to str() function, it is used like that: age = 45 strAge = f'{age}' Python provides the str() function for that reason. Unlike in C++ and Java, Python variables don't contain explicit type information. If you're using a function that requires a string, you can pass variables of other types to it without throwing an exception, although your code may throw an exception when it tries to process the variable. This tutorial went over the basics of working with the string data type in the Python 3 programming language. Creating and printing strings, concatenating and replicating strings, and storing strings in variables will provide you with the fundamentals to use strings in your Python 3 programs.

String Formatting with str.format() in Python 3 | DigitalOcean

Introduction. Python’s str.format() method of the string class allows you to do variable substitutions and value formatting. This lets you concatenate elements together within a string through positional formatting.. This tutorial will guide you through some of the common uses of formatters in Python, which can help make your code and program more readable and user friendly. In Python, strings are sequences of characters, which are effectively stored in memory as an object. Each object can be identified using the id() method, as you can see below. Python tries to re-use objects in memory that have the same value, which also makes comparing objects very fast in Python:

Home » Python » Python Concatenate String and int Python supports string concatenation using + operator. In most of the programming languages, if we concatenate a string with an integer or any other primitive data types, the language takes care of converting them to string and then concatenate it. Strings in python are contiguous series of characters delimited by single or double quotes. Python doesn't have any separate data type for characters so they are represented as a single character string.
