Python type conversion, numeric manipulation

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])  Create a complex number str (x) to                 convert an object x to a string repr (x) to                convert an object x to an expression string eval (str)              to evaluate a valid Python expression in a string and return an object tuple (s) Converts a               sequence s to a tuple list (s) converts a                sequence s to a list Chr (x) converts                 an integer to a 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 formatted (string only) S[i]                    index S[I:J]                slice x in S, X is in s< c6/> dependency for X in S:            iteration len (s)                  length min (s)                  min element max (s)                  max element S[i] = x               is s[i] re-assignment s[i:j] = R re-            assigns list fragment Value del s[i]               Delete an element from the list del s[i:j]            delete a fragment from the list

Numeric operation:

X << y                  left x >> y                  right shift x & Y bitwise                   and X | y bitwise                   or x ^ y bitwise                   XOR (exclusive OR) ~x bitwise                      Rollover x + y                   plus X- Y                   minus x * y                   multiply x                   /y general except X//y                  floor except × * * * y powers                  (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 (×, y [, modulo])    return (x * y) x% Modu Loround (x, [n])           rounded, n is the number of decimal places x < Y is                   less than x > y                   is greater than x = = y                  equals x! = y                  is not equal (same as <>) x >= y
  
    greater than or equal to x <= y is                  less than or equal
