This article introduces the knowledge of "binary conversion and string conversion in Python". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

One ten turns two

Convert decimal to binary:

> > bin (10)

'0b1010'

2 ten to eight

Convert decimal to octal:

> oct (9)

'0o11'

Three ten to sixteen

Convert decimal to hexadecimal:

Hex (15)

'0xf'

4 string to byte

Convert string to byte type

> s = "apple"

> bytes (srecoery encodingbirds utfmur8')

Baked apple`

5 converted to a string

Convert character types, numeric types, etc., to string types

> I = 100

> str (I)

'100'

6 + 10 rpm ASCII

ASCII characters corresponding to decimal integers

Chr (65)

'A'

7 ASCII to 10

Decimal number corresponding to ASCII character

> ord ('A')

sixty-five

8 convert to a dictionary

Several methods of creating data dictionary

> > dict ()

{}

> dict (axioms, girls, books, books, etc.)

{'await:' await, 'baked:' b'}

> dict (zip (['axiaojingzhongb'], [1pd2]))

{'averse: 1,' baked: 2}

> dict ([('axiaojin1), (' baked page2)]))

{'averse: 1,' baked: 2}

9 convert to floating point type

Convert an integer or numeric string to a floating point number

> > float (3)

3.0

If it cannot be converted to a floating point number, it will report ValueError:

> float ('a')

Traceback (most recent call last):

File "", line 1, in

Float ('a')

ValueError: could not convert string to float:'a'

10 convert to integer

Int (x, base = 10)

X may be a string or numeric value, converting x to an integer.

If the parameter is a string, it may contain symbols and decimal points.

If the integer representation is outside the range, a long integer is returned.

> int

eighteen

11 turn into a collection

Returns a set object. Duplicate elements are not allowed in the collection:

> a = [1, 4, 2, 3, 1]

> > set (a)

{1, 2, 3, 4}

12 turn to slice

Class slice (start, stop [, step])

Returns a slice object with an index set specified by range (start, stop, step), making the code more readable.

> a = [1, 4, 2, 3, 1]

> my_slice = slice (0meme 5pm 2)

> > a [my _ slice]
