Example:
As a side note, to convert to float, we can use float() in Python
2. Using float() function We first convert to float, then convert float to integer. Obviously the above method is better (directly convert to integer)
Output: class 'str' class 'str' 5.0 Note: float values are decimal values that can be used with integers for computation. IntroductionPython allows you to convert strings, integers, and floats interchangeably in a few different ways. The simplest way to do this is using the basic Before we get in to converting strings to numbers, and converting numbers to strings, let's first see a bit about how strings and numbers are represented in Python. Note: For simplicity of running and showing these examples we'll be using the Python interpreter. StringsString literals in Python are declared by surrounding a character with double (") or single quotation (') marks. Strings in Python are really just arrays with a Unicode for each character as an element in the array, allowing you to use indices to access a single character from the string. For example, we can access individual characters of these strings by specifying an index:
NumericsA numeric in Python can be an Integers can be a positive or negative whole number. Since Python 3, integers are unbounded and can practically hold any number. Before Python 3, the top boundary was 231-1 for 32-bit runtimes and 263-1 for 64-bit runtimes. Floats have unlimited length as well, but a floating-point number must contain a decimal point. Complex
numerics must have an imaginary part, which is denoted using
Converting Strings to NumericsUsing the int() FunctionIf you want to convert a string to an integer, the simplest way would be to use
This works as expected when you're passing a string-representation of an integer to
This same exception will even be raised if a valid float string is passed:
The
The same can be done for any other base, like hexadecimal (base 16):
Using the float() FunctionConverting string literals to floats is done via the
Notice that the resulting value is not entirely accurate, as it should just be The Check out our hands-on, practical guide to learning Git, with best-practices, industry-accepted standards, and included cheat sheet. Stop Googling Git commands and actually learn it!
Unlike However, it will raise an exception if a non-numeric value is passed to it:

As you can see, however, this should not be used as a more flexible replacement for Converting Numerics to StringsUsing the str() FunctionThe The function
The nice thing about Using the format() FunctionAnother
way of converting numerics to strings is using the To use the function, simply write a string followed by Here's an example:
The arguments in the
Note that
underneath the hood, the ConclusionPython allows you to convert strings, integers, and floats interchangeably in a few different ways. The simplest way to do this is using the basic How do I convert a string to a number?In Java, we can use Integer.valueOf() and Integer.parseInt() to convert a string to an integer.. Use Integer.parseInt() to Convert a String to an Integer. This method returns the string as a primitive type int. ... . Use Integer.valueOf() to Convert a String to an Integer. This method returns the string as an integer object.. How do you convert data type in Python?To convert between types, you simply use the type name as a function. There are several built-in functions to perform conversion from one data type to another. These functions return a new object representing the converted value.
How do you convert string to integer in Python?To convert a string to integer in Python, use the int() function. This function takes two parameters: the initial string and the optional base to represent the data. Use the syntax print(int("STR")) to return the str as an int , or integer.
