What does b in front of string mean?

bytes The b literal in front of the string literal means that the given string is in bytes' format. The b literal converts string into byte format. In this format bytes are actual data and string is an abstraction. A byte is a collection of 8 bits.

A string is a collection of characters that can represent a single word or a complete phrase. Since you can directly assign strings in Python to a literal (unlike other technologies) it is easy to use them. Python includes a number of built in functions and methods to perform various operations on strings, a string is an object of the String class, which contains these methods. In this article, we are going to find out what is the b character that is present in front of a string literal does in python. The b literal in front of the string literal means that the given string is in bytes’ format. The b literal converts string into byte format. In this format bytes are actual data and string is an abstraction. A byte is a collection of 8 bits. A string is a collection of Unicode characters (UTF – 16, UTF 32) or ASCII, whereas a byte is a collection of octets (0 255). The advantage of this process is that if we create a byte object it is directly stored in the computer’s disk, whereas if a string object is created it is first converted into a byte object then it is stored. So, by directly creating a byte object we are saving time. In Python 2, the prefix 'b' or 'B' is disregarded. Bytes literals in Python 3 are always prefixed with 'b' or 'B', and they yield a bytes type instance rather than a str type instance. They can only contain ASCII characters, and bytes with a numeric value of 128 or more must use escapes. Python 3.x distinguishes between the following types − literals = a series of Unicode characters str = '...' (UTF 16 or UTF 32) literals = a series of octets bytes = b'..' (integers between 0 and 255)

Example

In the example given below, we are taking 2 input strings and checking if they are of same data type after the addition of b literal. str1 = "Welcome to Tutorialspoint" str2 = b"Welcome to Tutorialspoint" print ( "The data type of the first string is" ) print ( type ( str1 ) ) print ( "The data type of the second string is" ) print ( type ( str2 ) )

Output

The output of the above example is,

The data type of the first string is The data type of the second string is

B Chord

The B major triad, more commonly called the B major chord or simply the B chord for short, consists of the notes B, D-sharp and F-sharp. Here it is on the treble clef staff:

… and on the piano:

As B major triad, the B chord consists of a major third plus a minor third. The interval from B to D-sharp is a major third, while the interval between D-sharp and F-sharp is a minor third.

Inversions of the B Chord

If the root of the B chord – B – is the bass note (i.e., the bottom note), then the chord is in root position: If the third of the chord – D-sharp – is the bottom note, then the chord is in first inversion: If the fifth of the chord – F-sharp – is the bass note, then the chord is in second inversion. (F-sharp is called the fifth of the chord because the interval from the root B to F-sharp is a fifth.)

B Major Arpeggios

If the notes of a chord are played one after the other, the chord is said to be arpeggiated. Here are the standard fingerings for arpeggios of the B chord. Make sure you learn these fingerings!

B major arpeggio in root position:

B major arpeggio in first inversion:

B major arpeggio in second inversion:
