Python中收益和回报之间的区别

Python产量
它通常用于将常规Python函数转换为生成器。生成器是Python中的一个特殊函数，它将生成器对象返回给调用者。由于它存储局部变量状态，因此控制了内存分配的开销。

例子：

# Python3 code to demonstrate yield keyword 
  
# Use of yield
def printresult(String) : 
    for i in String: 
        if i == "e": 
            yield i 
  
# initializing string 
String = "GeeksforGeeks" 
ans = 0
print ("The number of 'e' in word is : ", end = "" ) 
String = String.strip() 
  
for j in printresult(String): 
    ans = ans + 1
  
print (ans) 

输出：

The number of 'e' in word is : 4

Python返回
它通常用于执行结束并将结果“返回”给调用者语句。它可以返回所有类型的值，当没有带有“return”语句的表达式时，它返回 None。

例子：

# A Python program to show return statement 
class Test:  
    def __init__(self):  
        self.str = "GeeksForGeeks"
        self.x = "Shubham Singh"   
      
# This function returns an object of Test  
def fun():  
    return Test()  
          
# Driver code to test above method  
t = fun()   
print(t.str)  
print(t.x) 

输出：

GeeksForGeeks
Shubham Singh

Python yield 和 Return 之间的区别

S.NO.	YIELD	RETURN
1	Yield is generally used to convert a regular Python function into a generator.	Return is generally used for the end of the execution and “returns” the result to the caller statement.
2	It replace the return of a function to suspend its execution without destroying local variables.	It exits from a function and handing back a value to its caller.
3	It is used when the generator returns an intermediate result to the caller.	It is used when a function is ready to send a value.
4	Code written after yield statement execute in next function call.	while, code written after return statement wont execute.
5	It can run multiple times.	It only runs single time.
6	Yield statement function is executed from the last state from where the function get paused.	Every function calls run the function from the start.
