I wanted to know if there's any way of converting a string in python into a variable name and assigning it a default value. For example suppose I had this loop,
for i in range(1,4):
"User"+str("i")=0
It would give me the variables User1, User2 & User3 assigned a default value 0 which I can modify at my discretion.
I know this is possible to do using files but is there another way to do it?
You could do it with eval but generally I would suggest using a dict to store keys (variable names) and associated values:
users = {}
for i in range(1,4):
users["User"+str(i)]=0
print users
# {'User1': 0, 'User2': 0, 'User3': 0}
you can aceess each variable by just accessing the dictionary with the right key:
print users['User1']
# 0
See locals and globals as in
for i in range(1,4):
globals()["User"+str(i)] = 0
Then User2 will be in global scope for example
You can use eval(), https://docs.python.org/2/library/functions.html#eval
eval(varname + "=" + value);
eval does not work for statement (assignment is a statement) but only for expression.
