Lesson1_Function_Variables

## From 'hello.py'
# # Defining variables
# def hello(to):
#     print("hello,", to)

# # Ask user for their name
# name = input("What's your name? ")

# hello(name)


# # Can assign defaults
# def hello(to="world"):
#     print("hello,", to)

# hello()
# # Ask user for their name
# name = input("What's your name? ")

# hello(name)


# How to properly code so that you do not need to keep adding more code above, instead of below
def main():
    name = input("What's your name? ")
    hello(name)

def hello(to="world"):
    print("hello,", to)

main()





### from 'calculator.py'
# ## INTEGERS (int)
# x = input("What's x? ")
# y = input("What's y? ")

# z = int(x) + int(y) # you need to identify x and y as integers

# print(z)


# ## Another better approach
# x = int(input("What's x? "))
# y = int(input("What's y? "))

# print(x + y)


# ## Float: Number with a decimal point
# x = float(input("What's x? "))
# y = float(input("What's y? "))

# print(x + y)


# ## Floats + Rounding numbers
# x = float(input("What's x? "))
# y = float(input("What's y? "))

# z = round(x + y)

# print(z)


# ## Specify commas within triplets of digits such as 1,000 instead of default 1000.
# x = float(input("What's x? "))
# y = float(input("What's y? "))

# z = round(x + y)

# print(f"{z:,}") # note this is a format string, so that python doesn't simply print out 'z'
# # by adding the ':,' within the format string this will add the ,


# ## Using division
# x = float(input("What's x? "))
# y = float(input("What's y? "))

# z = round(x / y, 2) # the 2 specifies where to round!

# print(z)



# ## Another approach to the above
# x = float(input("What's x? "))
# y = float(input("What's y? "))

# z = x / y

# print(f"{z:.2f}") # specfy how many digits you want to print! So this will print to 2 decimals


# ## Defining and using return function
# def main():
#     x = int(input("What's x? "))
#     print("x squared is", square(x))


# ## Adding a square root
# def square(n):
#     return n * n

# main()


# ## Similar to the above you can use '**' to use as the power of
# def main():
#     x = int(input("What's x? "))
#     print("x squared is", square(x))


# ## Adding a square root
# def square(n):
#     return n ** 2 

# main()



## Additionally, you can use the function pow to also use as power of
def main():
    x = int(input("What's x? "))
    print("x squared is", square(x))


## Adding a square root
def square(n):
    return pow(n, 2)

main()



### From 'function_variables.py'
# input("What's your name? ")
# print("hello, Robby")

# # Variables: Ask user for their name
# name = input("What's your name? ") # name is the variable. equal is the 'assign' function

# # Say hello to user
# print("hello,") 
# print(name)

# Comments and psuedocode are correlated because you can add several comments so that you can later include actual code
# You can also use ' """ ' comment '"""" '


# # Variables: Ask user for their name
# name = input("What's your name? ") # name is the variable. equal is the 'assign' function

# # Say hello to user
# print("hello,", name) 


# # Strings (str)
# name = input("What's your name? ") 

# # Say hello to user
# print("hello,", end="") # this eliminates the default of hello being in one line and the name on the second line in the output
# print(name)


# # Goal code:
# name = input("What's your name? ") 

# # Say hello to user
# print(f"hello, {name}") 


# # Strings, adding more funcitons
# name = input("What's your name? ") 

# # Remove white space from string and Capitalize user's name and lastname
# name = name.strip()

# # Capitalize user's name and lastname
# name = name.title()

# # Say hello to user
# print(f"hello, {name}") 


# # Same code above but condensed!
# name = input("What's your name? ").strip().title()

# # Say hello to user
# print(f"hello, {name}") 


# # Splitting lastname
# name = input("What's your name? ").strip().title()

# # Split user's name into first and last name
# first, last = name.split(" ")

# # Say hello to user
# print(f"hello, {first}")
