for循环中pass和continue的区别:

那么为什么要传入python呢?

如果你想创建一个空类，方法或块。

例子:

class MyException(Exception):
    pass


try:
   1/0
 except:
   pass

在上面的例子中没有'pass'将抛出IndentationError。

x = [1,2,3,4] 
for i in x:
    if i==2:
         pass  #Pass actually does nothing. It continues to execute statements below it.
         print "This statement is from pass."
for i in x:
    if i==2:
         continue #Continue gets back to top of the loop.And statements below continue are executed.
         print "This statement is from continue."

输出为

>>> This statement is from pass.

同样，让我们运行相同的代码，只做了一些小更改。

x = [1,2,3,4]
for i in x:
    if i==2:
       pass  #Pass actually does nothing. It continues to execute statements below it.
    print "This statement is from pass."
for i in x:
    if i==2:
        continue #Continue gets back to top of the loop.And statements below continue are executed.
    print "This statement is from continue."

输出为-

>>> This statement is from pass.
This statement is from pass.
This statement is from pass.
This statement is from pass.
This statement is from continue.
This statement is from continue.
This statement is from continue.

Pass什么都不做。计算不受影响。但是继续返回到循环的顶部继续进行下一个计算。

Pass可以用于这样的场景:当你需要一些空函数、类或循环用于未来的实现，并且不需要执行任何代码时。 Continue用于以下情况:当在循环中满足某些条件时，需要跳过当前迭代并移动到下一个迭代。

它们之间有区别，continue跳过循环的当前迭代并执行下一个迭代。Pass什么都不做。它是一个空语句占位符。 我想给你们举个例子，能更好地说明这一点。

>>> some_list = [0, 1, 2]
... for element in some_list:
...     if element == 1:
...         print "Pass executed"
...         pass
...     print element
... 
0
Pass executed
1
2

... for element in some_list:
...     if element == 1:
...         print "Continue executed"
...         continue
...     print element
... 
0
Continue executed
2

是的，这是有区别的。Continue实际上跳过了当前循环迭代的其余部分(返回到开始)。Pass是一个空语句，不执行任何操作。

查看python文档

Pass只是继续循环或条件。它什么都不做。不过，Continue用于跳过当前迭代，并进入下一个迭代。

你可能会问，如果不需要，为什么要使用pass呢?考虑以下情况:

text = "I am a coder."

if text == "I am not a coder.":
    print("Programming is interesting! You should try it out!")
elif text == "I am a coder.":
    pass

Pass只是一个语法占位符，用来填充一些空间。如果在检查出特定条件时不想做任何事情，可以使用pass作为占位符。在Python中不能只编写空的条件、循环或函数。
