A detailed example of print function usage in Python3.2

This example describes the use of the print function in Python3.2. Share to everyone for your reference. The specific analysis is as follows:

1. Output string

?

1 2 3

>>> Strhello = "Hello World" >>> print (Strhello) Hello World

2. Formatted output integer

Support parameter formatting, similar to the C language printf

?

1 2 3

>>> Strhello = "The length of (%s) is%d"% (' Hello World ', Len (' Hello World ')) >>> print (Strhello) The L Ength of (Hello World) is 11

3. Formatted output 16, decimal, octal integers

#%x---hex hex

#%d---Dec decimal

#%o---Oct octal

?

1 2 3

>>> Nhex = 0xFF >>> print ("Nhex =%x,ndec =%d,noct =%o"% (nhex,nhex,nhex)) Nhex = Ff,ndec = 255,noct = 377

4. Formatted output floating-point number (float)

?

1 2 3 4 5 6 7 8 9

Import Math >>> print (' pi=%f '%math.pi) pi=3.141593 >>> print ("PI =%10.3f"% math.pi) PI = 3.142 >&G t;> print ("PI =%-10.3f"% math.pi) pi = 3.142 >>> print ("PI =%06d"% int (math.pi)) pi = 000003

5. Formatted output floating-point number (float)

?

1 2 3 4 5 6 7 8

>>> precise = 3 >>> print ("%.3s"% ("python") pyt >>> precise = 4 >>> print ("%.*s" % (4, "Python")) Pyth >>> print ("%10.3s"% ("python") PYT

6. Output lists (list)

Output list

?

1 2 3

>>> lst = [1,2,3,4, ' python '] >>> print (LST) [1, 2, 3, 4, ' Python ']

Output dictionary

?

1 2 3

>>> d = {1: ' A ', 2: ' B ', 3: ' C ', 4: ' d '} >>> print (d) {1: ' A ', 2: ' B ', 3: ' C ', 4: ' d '}

7. Automatic line Wrapping

Print automatically adds a carriage return at the end of the line, and if you do not need to enter, simply add a comma "," at the end of the print statement, and you can change its behavior.

?

1 2 3 4 5 6 7 8 9

>>> for I in Range (0,6): Print (I,) 0 1 2 3 4 5

or use the following function directly to output:

?

1 2 3

>>> Import sys >>> sys.stdout.write (' Hello World ') Hello World
