# Variables

# 1. Write a statement that creates a variable named my_var
# with a value "let's practice"

my_var = "let's practice"
#print(my_var)


# 2. What type is my_var?
# Write a statement to display the type of the variable my_var
print(type(my_var))


# 3. Reassign any integer value to my_var
my_var = 96

# 4. What type is my_var?
# Write a statement to display the type of the variable my_var
print(my_var)
print(type(my_var))



# 5. Consider variable naming convention
# Which one is valid? Whice one is good practice in Python?
number_of_slices_of_bacon = 100    # a.
badVariableName = "Java"           # b.


# 6. Write a statement that display an addition of two integers (5 and 9)
sum = 5 + 9
print(sum)


# 7. Write a statement that display a concatenation of three strings "input", "and", "output"
# separated by a space

string = "input " + "and" + " " + "output"
print(string)


# 8. Consider the following statements. What are differences?
print(9.5 / 2.3)                     # a.
print(format(9.5 / 2.3, ".7f"))      # b.
print(format(9.5 / 2.3, ".2f"))      # c.
print(format(9.5 / 2.3, ".2%"))      # d.
print(format(9.5 / 2.3, ".1f"))


# 9.Write a statement that displays a raise of an integer to an integer power
# (let's say 2 to the power of 3)
power = 2 ** 3
print("2 ** 3 = " + str(power))

# 10. Write a statement that displays the remainder of division of 25 / 6

print("remainder = " + str(25 % 6))


# determine if 11 is an odd or even
print(11 % 2)
if 11 % 2 == 1:
    print("odd")
else:
    print("even")



# 11. Consider the following statements. What are differences?
print("integer division : " + str(6 // 4))
print("division : " + str(6 / 4))



# 12. Write a statement to get an input from a keyboard (i.e., user's input)
# and store this input in a variable called "your_name"
# let's ask "What is your name ?"
# and display "Hello, " followed by value stored in your_name



# 13. Consider the following statement
number = int(input("Give me a number between 0 and 100: "))
print(type(number))    # what do we get from this statement?

number = int(number) + 4
print(type(number))    # what do we get from this statement?


# 14. Consider the following statements. What happens?
#number number / 0
number = number / 0
