# just a small shortcut that might help you guys:
# for eg:
name = "Crossroads"
age = 1
# so ...usually.. you print like this
:
# print("Hi " + name + " so you are almost" + str(age) + " year old!")
# instead, this is the shorthand trick ..if you want to call it
print(f'Hi {name} so you are almost {age} year old')
# Try it out and see what suits you!

[viper_solo]

if anyone's wondering about the local variable, issue (value=value+1).

when u try to "assign" a global variable name, in function, it becomes a local variable ie, (value=value+1), here no connection to global (as assignment comes it is considered as local variable), soo the error came as value is not defined in function for the value='value'+1 quoted value.
additionally, s=value+1 worked because we are using the global name, no assignment just fetching the global value.
