I want to create variables as a1,a2,a3...a10.
For that I used a for loop. As the variable in loop increments I need to create a variable as above.
Can anyone give me an idea?
At the time of creation I also need to be able to assign values to them.
That's where I'm getting syntax error.
Usually, we use a list, not a bunch of individual variables.
a = 10*[0]
a[0], a[1], a[2], a[9]
Following what S.Lott said, you can also use a dict, if you really nead unique names and that the order of the items is not important:
data = {}
for i in range(0, 10):
data['a%d' % i] = i
>>>data
{'a1': 1, 'a0': 0, 'a3': 3, 'a2': 2, 'a5': 5, 'a4': 4, 'a7': 7, 'a6': 6, 'a9': 9, 'a8': 8}
I would add that this is very dangerous to automate variable creation like you want to do, as you might overwrite variables that could already exist.
globals() returns the global dictionary of variables:
for i in range(1,6):
globals()["a%i" % i] = i
print a1, a2, a3, a4, a5 # -> 1 2 3 4 5
But frankly: I'd never do this, polluting the namespace automagically is harmful. I'd rather use a list or a dict.
You can use the exec function:
for i in range(0,10):
exec("a%d=%d" % (i,i))
Not very pythonic way of doing things.
