Can you explain the strings in Python

[ebn852_pan]

x = 2
x = str(x)
print("Years on the force is "  + x)

Years on the force is 2 #Casting. 2 is not string but a int. Python sees this as a string or int? Never mind. I got it. x = str(2) is a conversion to string from an integer. So you put a string on the inside of print.

str(x) is not a cast. str(x) creates a new str object which is the string representation of the value of x.

x is a variable. x is never an int or a str, it is a name that is used to reference different objects. Kind of like a key in a dictionary. In fact, "x" is a key in a dictionary you can reference by calling locals().

x = 2
print(locals()["x"], id(x), type(x))
x = str(x)
print(locals()["x"], id(x), type(x))

Output:
2 140726717440840 <class 'int'>
2 2176490884464 <class 'str'>

id() prints the ID of an object. id(x) prints the ID of an object referenced by "x".

The first print shows that x references an int object. The second print shows x references a str object. The two objects have different ID's, proving they are completely different objects.

Thanks. I get the idea. Those are the in built methods. locals()

Years on the force is 15
2 138810210880456 <class 'int'>
2 138810198583792 <class 'str'>

Just use f-string, no need for str()

x = 2
print(f"Years on the force are {x}")

You can even put a function in the curly brackets!

x = 2
y = 2
def add(a, b):
    return a+b

print(f"Years on the force are {add(x, y)}")
