How do you define a long variable in python?
Python interpreter allocates memory based on the data type of variable. Therefore, by assigning different data types to variables, you can store integers, strings and longs. Show
For specific to long type, you can append "l" or "L" in the value, caps "L" is recommended. Python displays long integers with an uppercase L
For variable "f", while displaying the value interpreter has appended "L" with value. As mentioned by Kasra, in Python 2.x you can typecast variable type with long(), but this is no longer supported in Python 3. This is not required as Python interpreter usually takes care if value changes, until unless you want to do it explicitly Number data types store numeric values. They are immutable data types. This means, changing the value of a number data type results in a newly allocated object. Number objects are created when you assign a value to them. For example − var1 = 1 var2 = 10 You can also delete the reference to a number object by using the del statement. The syntax of the del statement is − del var1[,var2[,var3[....,varN]]]] You can delete a single object or multiple objects by using the del statement. For example − del var del var_a, var_b Python supports different numerical types −
It is possible to represent an integer in hexa-decimal or octal form >>> number = 0xA0F #Hexa-decimal >>> number 2575 >>> number = 0o37 #Octal >>> number 31 ExamplesHere are some examples of numbers.
A complex number consists of an ordered pair of real floating-point numbers denoted by a + bj, where a is the real part and b is the imaginary part of the complex number. Number Type ConversionPython converts numbers internally in an expression containing mixed types to a common type for evaluation. Sometimes, you need to coerce a number explicitly from one type to another to satisfy the requirements of an operator or function parameter.
Mathematical FunctionsPython includes the following functions that perform mathematical calculations.
Random Number FunctionsRandom numbers are used for games, simulations, testing, security, and privacy applications. Python includes the following functions that are commonly used.
Trigonometric FunctionsPython includes the following functions that perform trigonometric calculations.
Mathematical ConstantsThe module also defines two mathematical constants −
How do you declare a variable as long in python?Type int(x) to convert x to a plain integer. Type long(x) to convert x to a long integer.
How do you handle long numbers in python?Python supports a "bignum" integer type which can work with arbitrarily large numbers. In Python 2.5+, this type is called long and is separate from the int type, but the interpreter will automatically use whichever is more appropriate.
Is there long int in python?Python currently distinguishes between two kinds of integers (ints): regular or short ints, limited by the size of a C long (typically 32 or 64 bits), and long ints, which are limited only by available memory.
How do I define a variable in python?Rules for creating variables in Python
A variable name must start with a letter or the underscore character. A variable name cannot start with a number. A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ ).
