 函数定义

def print(self, *args, sep=' ', end='\n', file=none): # known special case of print
    """
    print(value, ..., sep=' ', end='\n', file=sys.stdout, flush=false)
    prints the values to a stream, or to sys.stdout by default.
    optional keyword arguments:
    file:  a file-like object (stream); defaults to the current sys.stdout.
    sep:   string inserted between values, default a space.
    end:   string appended after the last value, default a newline.
    flush: whether to forcibly flush the stream.

　　"""

函数用法

# 1.用法
print('hello world!')
name = '小白'
print(name)

#2.用法：print(name,age,gender)
age =18
gender ='boy'
print(name,age,gender)  # sep默认的分割是空格

# 3.用法： print(value1,value2,value3,...,sep=' ',end='\n')
print(name,age,gender,sep='-') # sep=‘*’  sep='$'  sep='-'

print() 函数的 flush 参数用于控制输出缓存，该参数一般保持为 false 即可，这样可以获得较好的性能。
