python type conversion

function                                                                                                                                                                                 Type conversion Convert x to a floating point number

complex(real [,imag ]) Create a complex number

str(x ) Convert object x to string

repr(x ) Convert object x to expression string

eval(str ) Converts the sequence s to a tuple

list(s ) Converts the sequence s to a list

chr(x ) Convert an integer to a character

unichr(x ) Convert an integer to a Unicode character

ord(x ) Convert a character to its integer value

hex(x ) Convert an integer to a hexadecimal Base string

oct(x) Convert an integer to an octal string

The sequence supports the following operations:

Operations Sequence connection

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

s % d                     String formatting (only strings)

s[i]                                  --                                                                

x in s , x not in s Subordination relationship

for x in s : Iteration

len(s) Length

min(s) Minimum element

max(s) Maximum element

s[i ] = x           Reassign s[i]

s[ i:j ] = r

x

x ^ y                                            . +y

x// y mod y )

-x                                                                                                                                                                                                                                                                 ​

abs(x) Absolute value

divmod(x,y) Return (int(x / y ), x % y )

pow(x ,y [,modulo ]) Return (x ** y ) x % modulo

round(x ,[n]) Rounding, n is the decimal point Digits

Yx >x> y is greater than

x == y equal to

x! = Y is not equal to (the same as

)

x> = y greater than equal to

x
