On my recent project I am facing with new obstruction where I need to declare a variable based on value of another string.
What I need:
'Hai'= 2
The String Hai is initialized at variable x,
x='hai' then I need 'hai'= 2
Now all I want is the value of x to point to a int (different int for different values of x).
So if,
x='bye'
then,
'bye'=20
As mentioned in the comments, you are describing a dictionary:
A dictionary provides a mapping between two different values (also known as an associative array in other languages). You can declare one in Python like this:
mydict = {"hai": 2, "bye": 20}
print(mydict["hai"])
# 2
print(mydict["bye"])
# 20
You can then use variables as the key to access the dictionary:
mykey = "bye"
print(mydict[mykey])
# 20
For more details, please see the Python docs for dictionaries
You need to get a dictionary as @Saadat said:
x = {'hai': 2, 'bye': 20}
Now
x['hai']
Will give 2 and the other key will give 20 Or:
y='hai'
z = x[y] #z=2
Also another worse approach:
if x == 'hai':
hai = 2
elif x == 'bye'
bye = 20
...
If you don't go with dictionary and need to declare a variable name & value at runtime. We can achieve this with setattr()
Try this,
class Sample:
pass
obj = Sample()
x = 'hai'
setattr(obj, x, 20)
print(obj.hai)
