want to use string as a variable name

Question

I am using python

a5 = [1.1,1.3,15.4,13.3]
# and 
numb = 5
aname = str('a')+str(numb) 
print(aname[0]) 

I want to make variable name using str and number and then want to get value of that variable

Answer 1

If your variables are global, then you can use globals()[aname] to get their value. If they are local, then use locals()[aname]

Answer 2

You Can Use Dictionary

name = "a"
value = True
a_dictionary = {name: value}
print(a_dictionary["a"])

the output will be True

Answer 3

What you want to use is the eval function (docs).

For your example:

a5 = [1.1,1.3,15.4,13.3]
# and 
numb = 5
aname = eval('a' + str(numb))
print(aname[0])
