Python Learning note 05-sequences, tuples

Sequence: Consists of a string, a tuple, a list

There are two features: You can use the index operator and the slice operator

Index can be negative, str[-1] means the last element is taken out

The slice operator is a sequence name followed by a square bracket

Basic operator: Len () to derive sequence length

Min () to derive the smallest value in the sequence

Max () draws the largest value in the sequence

+ Connect two sequences

* Repeating sequence elements, followed by repetitions

In determining whether a string is judged in a sequence, the character needs to be quoted.

CMP (STR1,STR2) compares two sequence values for the same greater than return 1, which is less than return-1, equals return 0

A variable can be applied when a label has no quotation marks, and a normal character is represented by quotation marks

Tuple: Definition mode t= ("A", 2, "D")

When you define a value, you enclose the quotation marks

Assignment Another method a,b,c= (one-way)
