Can we use the same variable name to store different values?

Yes, you can absolutely use the same variable name to store different values throughout your program!

In Python, when you assign a new value to an existing variable, the old value is replaced with the new one. This is part of what makes variables so flexible.

For example, consider this code:

age = 25  
print(age)  # This will print 25

age = 30  
print(age)  # This will print 30
  1. In the first step, age is assigned the value 25, and we print it.

  2. In the second step, we assign a new value 30 to the same variable age. When we print it again, it shows 30.

As you can see, you can reuse the variable name, and it will always reflect the most recent value you assigned to it.

However, be careful not to change the value to a different data type; for instance, assigning a text value to a variable that was originally storing a number:

age = 25  
print(age)  # This will print the number: 25

age = "John"  
print(age)  # This will print the text: John

While this is allowed in Python, it can create problems if you use the variable in some logical operation further down the line.

If you have more questions about this or anything else, feel free to ask. Hope this helps!
