Lambda expression +python built-in functions

The traditional way of defining functions is as follows

def F1 ():     return 123

Lambda expression definition function

Lambda : 123

Python3 built-in functions

1.abs Absolute Value

i = ABS ( -11)print (i)

The output is 11.

ABS = Absolute

2,all loop parameter, returns True if each element is true

R = All ([true, True])print (r)

In Python 0 () [] ' and none are false (Null values are false)

R = All (["123","" ", [up],""])print (r)

Return to False

3,any as long as one is true

i = any ([None,"","123"])print (i)

Return to True

4,ASCII automatically executes ASCII (object) to the class of the object, look for __reper__, get the return value

class Foo:     def __repr__ (self):         return " Hello "  == ASCII (obj)print (r)

The return value is Hello

5,bin () binary Oct () octal int () decimal hex () hex

6,bool judge true or false: essentially converts an object to a Boolean value

7,bytes (bytes) bytesarray (byte list)

Complement the conversion between bytes and strings

Bytes ("xxxxx", encoding= "Uft-8")

8,CHR () Ord ()

c = Chr (65)

Print (c)

The return value is a

Chr finds the corresponding ASCII code character (ASCII is a character corresponding to a byte)

Same as Ord (a)

Returns 97 converts a character to a number by Ord
