A detailed description of the use of lists and tuples in Python

This article mainly introduces the definition and use of Python list and tuple, and analyzes the function, difference, definition and use of the list and tuple in Python in the form of instance, which can be referenced by friends.

The examples in this article describe the definition and use of Python lists and tuples. Share to everyone for your reference, as follows:

#coding =utf8print "can use lists and tuples as normal" arrays ", which can hold any number of arbitrary types of Python objects. Lists and tuples access elements through a numeric index (starting at 0).             Differences between lists and tuples:------------------------------------------------------------------------------------tuples \  List------------------------------------------------------------------------------------list elements with brackets [] \  Tuple elements with parentheses () the number of elements and the value of the element can be changed \ The number of elements and the value of the element cannot be changed------------------------------------------------------------------------------------tuples can see a read-only list. Lists and tuples can be obtained by using the index operator ([]) and the Slice operator ([:]) to get a subset of ' numberlist=[1,2,3,4,5,6,7,8.9,0101,017,0xab]stringlist=[' hello ', "hello World "," ' goddness ' ']mixlist=[12,13.2,01, ' abc ', ' Hello ']numbertouple= (1,2,3,4,5,6,7,8.9,0101,017,0xab) stringtouple= (' Hello ', ' Hello World ', ' ' goddness ') mixtouple= (12,13.2,01, ' abc ', ' Hello ') print "Output the element Of the NumberList by index---------> ", numberlist[0],numberlist[1],numberlist[2],numberlist[-1]print" output the element of the Stringlist by index---------> ", Stringlist[0],stringlist[1],stringliSt[2],stringlist[-1]print "Output the element of the Mixlist by index--------->", Mixlist[0],mixlist[1],mixlist[2], Mixlist[-1]print "Output the element of the Numbertouple by index--------->", Numbertouple[0],numbertouple[1], Numbertouple[2],numbertouple[-1]print "Output the element of the Stringtouple by index--------->", Stringtouple[0], Stringtouple[1],stringtouple[2],stringtouple[-1]print "Output the element of the Mixtouple by index--------->", Mixtouple[0],mixtouple[1],mixtouple[2],mixtouple[-1]print "Output of the element of the numberlist by slice--------->" , numberlist[0:2],numberlist[1:3],numberlist[0:],numberlist[:-1]print "Output the element of the stringlist by Slice---------> ", stringlist[0:1],stringlist[2:3],stringlist[0:],stringlist[:-1]print" output the element of the Mixlist by Slice---------> ", mixlist[0:],mixlist[:1],mixlist[0:2],mixlist[2:-1]print" output the element of the Numbertouple by Slice---------> ", NUMBERTOUPLE[0:2],NUMBERTOUPLE[1:3],NUMBERTOUPLE[2:],numbertouple[:-1]print "Output the element of the stringtouple by slice--------->", Stringtouple[0:2], Stringtouple[1:3],stringtouple[2],stringtouple[-1]print "Output of the element of the mixtouple by slice--------->", Mixtouple[0:],mixtouple[1:3],mixtouple[2],mixtouple[:-1]numberlist[0]=59#numbertouple[0]=56print "Change the Value of numberlist[0] to------------', numberlist[0] #print "Can not change the value of numbertouple[0] to---------- --", numbertouple[0]
