What symbols are used to separate python statements?

Python statement separation: You can use syntactic bracket pairs. The statements in the bracket pairs can span several lines. You can also use backslash endings to have the same effect. You can also use parentheses. To separate, character constants have special rules and can be separated by three pairs of single quotes.

1. If you use syntax bracket pairs, the statement can span several lines

List:

>>> a=[2,3,4]
>>> b=[1,
       2,
          3,]
>>> a
[2,3,4]
>>> b
[1, 2, 3]
>>>

Dictionary:

>>> c={'a':1,'b':2,'c':3}
>>> d={'a':1,
             'b':2,
                   'c':3}
>>> c
{'a': 1, 'b': 2, 'c': 3}
>>> c
{'a': 1, 'b': 2, 'c': 3}
>>> d
{'a': 1, 'b': 2, 'c': 3}
>>>

2. If you use reverse With a slash at the end, the statement can span several lines

>>> if 2>1 and \
    2>0:	
        print(True)	
True
>>>

3. This method of use is not recommended because it is easy to make errors

We recommend using parentheses

>>> if (2>1 and 
    2>0):
	 print(True)
	
True
>>>

4. String constants have special rules

>>> string='''aaa
	bbb
	ccc'''
>>> string
'aaa\n\tbbb\n\tccc'
>>>
