Python print() function

Description

The print() method is used to print output, the most common function.

The flush keyword parameter was added in Python 3.3.

print is a function in Python3.x, but it is not a function in Python2.x, just a keyword.

Syntax

The following is the syntax of the print() method:

print(*objects, sep=' ', end='\n', file=sys.stdout, flush=False)

Parameters

objects -- plural, indicating that multiple objects can be output at one time. When outputting multiple objects, they need to be separated by ,.

sep -- Used to separate multiple objects. The default value is a space.

end -- used to set the ending. The default value is the newline character \n, we can change it to other strings.

file -- The file object to be written.

flush -- Whether the output is cached is usually determined by the file, but if the flush keyword argument is True, the stream will be forced to be flushed.

Return value

None.

Example

The following shows an example of using the print function:

Test under Python3

>>>print(1)  
1  
>>> print("Hello World")  
Hello World  
 
>>> a = 1
>>> b = 'runoob'
>>> print(a,b)
1 runoob
 
>>> print("aaa""bbb")
aaabbb
>>> print("aaa","bbb")
aaa bbb
>>> 
 
>>> print("www","runoob","com",sep=".")  # 设置间隔符
www.runoob.com

The effect of using the flush parameter to generate a Loading:

Example

import time
print("---RUNOOB EXAMPLE ： Loading 效果---")
print("Loading",end = "")
for i in range(20):
    print(".",end = '',flush = True)
    time.sleep(0.5)
