Decompression sequence

Example 1: The left value must be the same as the value on the right one by one, or it will be an error

1 >>> a,b,c={1,2,3}  #a =1,b=2,c=32 >>> a3 14 >>> b5 26 >>> C7 3

Example 2: The left value must be the same as the value on the right one by one, or it will be an error

1>>> a,b,c,d,e='Hello'   #decompression sequence, the left value must be the right value is one by one corresponding to the relationship, or will error2>>>a3 'h'4>>>b5 'e'6>>>C7 'L'8>>>D9 'L'Ten>>>e One 'o'

Example 3:

Take the first and last value of a list

1 >>> l=[10,3,2,3,5,1,2,3,5,8,9]2 >>> a,*_,c=l   #取第一个值和最后一个值  3 >>> a4 5 >>> C6 9

Example 4:

The value of a, B interchange position

1 # the value of a, B interchange position 2 3 >>> a=1 4 >>> b=2 5  6 >>> x=a  7 >&G t;> x  8 1 9 >>> a=b >>> b=x  One >>> a b (2, 1)

Example 5: Exchanging values for F1 and F2

1 # exchanging values for F1 and F2 2 3 >>> f1=1 4 >>> f2=2 5  6  7 >>> f1,f2=f2,f1< /c9> 8 >>> F1  9 2 >>> f2 1
