Python data type conversion

Python type conversion function description python type conversion

Function description

Int (x [, base]) converts x to an integer.

Long (x [, base]) converts x to a long integer.

Float (x) converts x to a floating point number.

Complex (real [, imag]) creates a plural number

Str (x) converts object x to a string

Repr (x) converts object x to an expression string

Eval (str) is used to calculate a valid Python expression in a string and return an object.

Tuple (s) converts the sequence s into a tuples

List (s) converts sequence s into a list

Chr (x) converts an integer to a character

Unichr (x) converts an integer to a Unicode character

Ord (x) converts a character into its integer

Hex (x) converts an integer into a hexadecimal string.

Oct (x) converts an integer into an octal string

The sequence supports the following operations:

Operation description

S + r sequential join

S * n, n * s n copies, n is an integer

S % d string formatting (string only)

S [I] Index

S [I: j] slice

X in s, x not in s subordination

For x in s: Iteration

Len (s) length

Min (s) minimum element

Max (s) maximum element

S [I] = x is s [I] re-assigned

S [I: j] = r: returns the list fragment value.

Del s [I] deletes an element from the list.

Del s [I: j] deletes a clip from the list.

Numeric operation:

X <y shifts left

X> y shift right

X & y

X | y by bit or

X ^ y exclusive or)

~ X flip by bit

X + y Plus

X-y subtraction

X * y multiplication

X/y

X // y floor Division

X ** y multiplication (xy)

X % y modulo (x mod y)

-X changes the symbol bit of the operand.

+ X does nothing.

~ X ~ X =-(x + 1)

Abs (x) absolute value

Pmod (x, y) returns (int (x/y), x % y)

Pow (x, y [, modulo]) returns (x ** y) x % modulo

Round (x, [n]) rounding, n is the number of decimal places

X <y is less

X> y is greater

X = y equals

X! = Y is not equal to (same as <>)

X> = y is greater than or equal

X <= y is less than or equal
