本文详细介绍了Python中常用的内置函数，包括chr(), ord(), str(), abs(), max(), min(), pow(), round()等。通过实例展示了如何使用这些函数进行字符转换、数学运算及数值处理等操作。

>>>ord('a') - ord('A')
32
>>>chr(98)  
'b'  
#chr(code ) function return the character represent by the code  
>>> str(98)  
'98'  
#notice the difference between str() and chr()

chr()
ord()
str()
abs(x) #return the absolute value for x
max(x1,x2,...) #return the largest among x1,x2,. . .
min(x1,x2,...) #return thesmallest among x1,x2,. . .
pow(a,b) #return a**b</p>
round(x,n) #return the float value rounded to n digits after the decimal point
round(x) #Return an integer nearest to x. If x is equally close to two integers,the even one is returned

>>>abs(-2)   # is 2
>>>max(1,5,2)# is 5  
>>>min(1, 5, 2) # is 1  
>>>pow(2, 3) #is 8  
>>>round(5.5) #is 6  
>>>round(5.4) # is 5  
>>>round(4.5) #is 4  
>>>round(5.446,2) #is 5.45  
>>>round(5.443,2) # is 5.44
