how to convert array into dictionary in python?-CodePudding

basically I want to know that how to convert array into dictionary in python.

import numpy as np
a=np.array(\[23,34,23,45,23\])
print(a)

output [23 34 23 45 23]

but i want

{0:"23",1:"34",2:"23",3:"45",4:"23"}

CodePudding user response：

It seems that the values in the array need to be converted to string when added to the target dictionary. Therefore:

import numpy as np
a = np.array([23,34,23,45,23])
d = dict(enumerate(map(str, a)))
print(d)

Output:

{0: '23', 1: '34', 2: '23', 3: '45', 4: '23'}

Iteratively by enumerate() and using f-formatting for dict-members

mydict={}
for index, i in enumerate(a):
    mydict[index]=f"{i}"
    
print(mydict)

CodePudding user response：

You can use comprehensions like

dic={i:a[i] for i in range(len(a))}
