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只是表示空什么都不做，如下所示:

for i in range(3):
    if i == 1:
        pass
    print(i)

输出:

0
1
2

Continue跳过当前循环进入下一个循环，如下所示:

for i in range(3):
    if i == 1:
        continue
    print(i)

输出:

0
2

是的，他们做的事情完全不同。Pass只是什么都不做，而continue则继续进行下一次循环迭代。在您的示例中，如果在if之后添加另一条语句，区别就会很明显:在执行pass之后，将执行这条进一步的语句。在继续之后，它就不会了。

>>> a = [0, 1, 2]
>>> for element in a:
...     if not element:
...         pass
...     print(element)
... 
0
1
2
>>> for element in a:
...     if not element:
...         continue
...     print(element)
... 
1
2

Continue将跳转回循环的顶部。Pass将继续处理。

如果pass位于循环的末尾，则差异可以忽略不计，因为流无论如何都会返回到循环的顶部。

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.

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。

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。
