Conversion between Python data types and python Data Types

Conversion between Python Data Types

Function	Description
Int (x [, base])	Converts x to an integer.
Long (x [, base])	Converts x to a long integer.
Float (x)	Convert x to a floating point number.
Complex (real [, imag])	Create a plural number
Str (x)	Convert object x to a string
Repr (x)	Convert object x to an expression string
Eval (str)	Used to calculate a valid Python expression in a string and return an object
Tuple (s)	Converts the sequence s into a single tuples.
List (s)	Converts sequence s to a list.
Set (s)	Convert to a variable set
Dict (d)	Create a dictionary. D must be a sequence (key, value) tuples.
Frozenset (s)	Convert to an unchangeable set
Chr (x)	Converts an integer to a character.
Unichr (x)	Converts an integer to a Unicode character.
Ord (x)	Converts a character to an integer.
Hex (x)	Converts an integer to a hexadecimal string.
Oct (x)	Converts an integer to an octal string.

Python mathematical functions

Function	Return Value (description)
Abs (x)	Returns the absolute value of a number. For example, abs (-10) returns 10.
Ceil (x)	Returns the upper integer of a number. For example, math. ceil (4.1) returns 5.
Cmp (x, y)	If x <y returns-1, if x = y returns 0, if x> y returns 1
Exp (x)	Returns the x power of e (ex). For example, math. exp (1) returns 2.718281828459045
Fabs (x)	Returns the absolute value of a number. For example, math. fabs (-10) returns 10.0
Floor (x)	Returns the rounded down integer of a number. For example, math. floor (4.9) returns 4.
Log (x)	For example, math. log (math. e) returns 1.0, math. log (2.0) returns
Log10 (x)	Returns the logarithm of x on the base of 10. For example, math. log10 (100) returns 2.0.
Max (x1, x2 ,...)	Returns the maximum value of a given parameter, which can be a sequence.
Min (x1, x2 ,...)	Returns the minimum value of a given parameter, which can be a sequence.
Modf (x)	Returns the integer and decimal parts of x. The numerical symbols of the two parts are the same as those of x, and the integer part is expressed as a floating point.
Pow (x, y)	The value after the x ** y operation.
Round (x [, n])	Returns the rounding value of floating point x. If n is given, it indicates the number of digits rounded to the decimal point.
Sqrt (x)	Returns the square root of number x. The number can be a negative number and the return type is a real number. For example, math. sqrt (4) returns 2 + 0j.

Python random number Function

Function	Description
Choice (seq)	Randomly select an element from the element of the sequence, such as random. choice (range (10), and randomly select an integer from 0 to 9.
Randrange ([start,] stop [, step])	Obtains a random number from a set that increments by the specified base number within the specified range. The default value of the base number is 1.
Random ()	The next real number is randomly generated within the range of [0, 1.
Seed ([x])	Change the seed of the random number generator. If you do not understand the principle, you do not need to set seed. Python will help you select seed.
Shuffle (lst)	Random sorting of all elements in a sequence
Uniform (x, y)	The next real number is randomly generated, which is within the range of [x, y.
