1name and age1
valid_name and _name
for and else
Name and name (treated as the same)
A student writes Name = "Aman" and later prints name. Based on case sensitivity, what will most likely happen?
It will print Aman because Python ignores case in variable names.
It will raise an error because Name and name are different identifiers.
It will print an empty line.
It will automatically convert Name to name.
You want to store a person's age without declaring a type first. According to the material, what is the correct approach in Python?
Declare the type int age; before assigning.
Use age = 17; Python decides the type automatically.
Use var age = 17 to signal dynamic typing.
You cannot store numbers without manual type declaration.

Only Positive number prints
Only This line is outside the if prints

Hello Aman
Who are you?

if marks > 40: print('Pass') else print('Fail')
if marks > 40: print('Pass') else: print('Fail')
print('Pass') if marks > 40 else print('Fail')

age = 20; AGE = age; print(AGE)
age = Age = 30; print(age)

a, b, c = 10, 20, 30; print(a, b, c)
a b c = 10 20 30; print(a, b, c)
(a, b, c) == (10, 20, 30); print(a, b, c)
