#  Variables
# box= "shoes"
# print(box)

# 4 big no no for variables naming
# 1.No Number sign before variable and middle and last is accepted

# 3. No space between variables
# my box= incorrect
# can write like this
# my_box= 'shoes'
# print(my_box)

# 4. varible should not be the name of print in function
# print= 'shoes'
# print(print)
