Conversions between arrays, tuples, dictionaries, and strings in Python

1. Dictionaries

Dictionary to String

>>> dict={' name ': ' Zhzhgo ', ' Age ':25}>>> print type (str (dict)), str (dict) <type ' str ' > {' age ': ' Name ': ' Zhzhgo '}>>>

Dictionary conversion to tuples

>>> dict={' name ': ' Zhzhgo ', ' Age ':25}>>> print type (tuple (dict)), tuple (dict) <type ' tuple ' > (' Age ', ' name ') >>>

Dictionary to List

>>> dict={' name ': ' Zhzhgo ', ' Age ':25}>>> Print type (list (dict)), List (dict) <type ' list ' > [' Age ' ', ' name ']>>>

2, meta-group

Tuples converted to strings

>>> mytupe= >>> Print mytupe.__str__ () (1, 2, 3) >>> >>> mylist= (' h ', ' e ', ' l ', ' l ', ' o ') >>> print '. Join (MyList) hello>>>

Tuples to List

>>> mytupe= (mytupe) >>> Print List [1, 2, 3]>>>

Tuples cannot be converted to dictionaries

3. List

List to String

>>> mylist=[' h ', ' e ', ' l ', ' l ', ' O ']>>> print '. Join (MyList) hello>>>

List to tuple

>>> mylist=[1,2,3]>>> Print Tuple (mylist) (1, 2, 3) >>>

List cannot be converted to dictionary

4. String

Convert string to tuple

>>> mystring= "Hello" >>> print tuple (mystring) (' H ', ' e ', ' l ', ' l ', ' o ') >>>

String to List

>>> mystring= "Hello" >>> Print List (mystring) [' H ', ' e ', ' l ', ' l ', ' O ']>>>

String to Dictionary

>>> mystring= "{' name ': ' Zhzhgo ', ' age ': +} ' >>> print type (eval (mystring)) <type ' Dict ' >> >>
