I need the file for Exercise 26

Good day Mr. Zed, I need the coding for exercise 25 to work out the errors for practice.
Thanks, I can’t get the file

print("How old are you?", end=' ')
age = input()
print("How tall are you?", end=' ')
print("How much do you weigh?", end=' '
weight = input()

print(f"So, you're {age} old, {height} tall and {weight} heavy.")

script, filename = argv

txt = open(filenme)

print("Here's your file {filename}:")

print("Type the filename again:")
file_again = input("> ")

txt_again = open(file_again)


print('Let's practice everything.')
print('You\'d need to know \'bout escapes 
      with \\ that do \n newlines and \t tabs.')

poem = """
\tThe lovely world
with logic so firmly planted
cannot discern \n the needs of love
nor comprehend passion from intuition
and requires an explanation
\n\t\twhere there is none.


five = 10 - 2 + 3 - 
print(f"This should be five: {five}"

def secret_formula(started)
    jelly_beans = started * 500
    jars = jelly_beans / 1000
    crates = jars  100
    return jelly_beans, jars, crates

start_point = 10000
beans, jars = secret_formula(start_point)

# remember that this is another way to format a string
print("With a starting point of: {}".format(start_point))
# it's just like with an f"" string
print(f"We'd have {beans} beans, {jars} jars, and {crates} crates.")

start_point = start_point / 10

print("We can also do that this way:")
formula = secret_formula(startpoint)
# this is an easy way to apply a list to a format string
print("We'd have {} beans, {} jars, and {} crates.".format(*formula))

people = 20
cates = 30
dogs = 15

if people < cats:
    print "Too many cats! The world is doomed!"

if people < cats:
    print("Not many cats! The world is saved!")

if people < dogs:
    print("The world is drooled on!")

if people > dogs
    print("The world is dry!")

dogs += 5

if people >= dogs:
    print("People are greater than or equal to dogs.")

if people <= dogs
    print("People are less than or equal to dogs.)

if people = dogs:
    print("People are dogs.")

hope that works this time.

Sorry about that. wasn’t copying in right for me.
