Print a list inside a dictionary without brackets

The following code:

a={"hello":[23,],90:["Hi",],25:[54,]}
for i in a:
    hrs=print(a[i],": ")

Has this output:

[23]:
["Hi"]:
[25]:

Whereas I need the output to be printed without the brackets like:

23:
"Hi":
25:

>Solution :

Try this:

a={"hello":[23,],90:["Hi",],25:[54,]}
for i in a:
    print(repr(a[i][0]), ':', sep='')

Output:

23:
'Hi':
54:
