The Magic day12 of the Python tuple

Tuple, the first level element cannot be modified, cannot be added or deleted

Tu = (111, ' Alex ', (11,22), [(33,44)],ture,33,33,)

It is recommended to add a comma at the end to distinguish whether the tuple is not an error

can be called out

Tu = (111,'Alex', (11,22), [(33,44)],true,33,33= tu[1]print(v )

or slice

Tu = (111,'Alex', (11,22), [(33,44)],true,33,33= tu[1:3]print (v)

Tuples after a tuple is sliced or set

can be used for loop

Tu = (111,'Alex', (11,22), [(33,44)],true,33,33,) for in Tu:     Print (item)

Lists and tuples can be converted to each other

Tu = (111,'Alex', (11,22), [(33,44)],true,33,33= list (TU)Print (v)

List = (111,'Alex', (11,22), [(33,44)],true,33,33= tuple (list)  Print(v)

is a string, you can connect through join

Tu = ['dsgsdgs','fhdshdsfh','sdgasgdas '  '_'. Join (TU)print(v)

Tuples are ordered.

Take a value of 33, the first "0" is taken out (33,44), the second takes 33

Tu = (111,'Alex', (11,22), [(33,44)],true,33,33= tu[3][0][0]Print (v)

Second-level list elements can be modified

Tu = (111,'Alex', (11,22), [(33,44)],true,33,33,) tu[3][0] =Print( Tu

Two ways to set up a tuple

Count gets the number of occurrences of the specified element in the tuple

Index gets the specific position of a value, the leftmost priority
