A detailed description of the type conversion method in Python

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 complex number

STR (x) converts an object x to a string

REPR (x) converts an object x to an expression string

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

Tuple (s) converts a sequence s to a tuple

List (s) converts the sequence s to a list

Chr (x) converts an integer to one character

UNICHR (x) converts an integer to a Unicode character

Ord (x) converts a character to its integer value

Hex (x) converts an integer to a hexadecimal string

Oct (x) converts an integer to an octal string

The sequence supports the following:

Operation description

S + R sequence connection

S * N, n * s S n times copy, n is integer

S% d string formatting (string only)

S[i] Index

S[I:J] Slices

X in S, X isn't in S dependency

For x in S: Iteration

Len (s) length

Min (s) min element

Max (s) max element

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

S[I:J] = R re-assigns the list fragment

Del S[i] Remove an element from the list

Del S[i:j] Delete a fragment from the list

Numeric operation:

x << y shift left

x >> y Shift Right

X & y Bitwise AND

x | Y bitwise OR

x ^ y bitwise XOR (exclusive OR)

~x rollover by bit

x + y Plus

X-y minus

X * y Multiply

X/y general except

X//Y floor except

X * * y-exponentiation (XY)

X% y modulo (x mod y)

-X Change the symbol bit of the operand

+x do nothing.

~x ~x=-(x+1)

ABS (x) absolute value

Divmod (x, y) return (int (× x/y), x% y)

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

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

x < y less than

x > Y greater than

x = = y equals

X! = y Not equal (same as <>)

x >= y is greater than or equal to

X <= y is less than or equal to
