Python FUNCTIONS Exercise for Beginners and Intermediate

Implement a function called my_func() that creates a variable add which stores the result of adding 20 and 30, and prints out the value of add. Don’t forget to also call the function!

50

def my_func():
    add = 20 + 30
    print(add)

my_func()

 Implement a function called my_func() that takes a single parameter x and multiplies it with 5, also returning the result when the function is called

result = my_func(20)
print(result)

100

def my_func(x):
    return x * 5

result = my_func(20)
print(result)

Implement a function called my_func() that takes two parameters x and y and divides x by y, also returning the result when the function is called.

result = my_func(32,8)
print(result)

4.0

def my_func(x, y):
    return x / y

result = my_func(32,8)
print(result)

Implement a function called my_func() that takes 3 parameters x, y and z and raises x to the power of y then adds z, also returning the result when the function is called.

result = my_func(3,3,3)
print(result)

30

def my_func(x, y, z):
    return x ** y + z

result = my_func(3,3,3)
print(result)

Implement a function called my_func() that takes a single parameter x and multiplies it with each element of range(5), also adding each multiplication result to a new (initially empty) list called my_new_list. Finally, the list should be printed out to the screen after the function is called.

result = my_func(2)
print(result)

[0, 2, 4, 6, 8]

def my_func(x):
    my_list = []
    for i in range(5):
        my_list.append(i * x)
    return my_list

result = my_func(2)
print(result)

Implement a function called my_func() that takes a single parameter x (a tuple) and for each element of the tuple that is greater than 4 it raises that element to the power of 2, also adding it to a new (initially empty) list called my_list. Finally, the code returns the result when the function is called.

result = my_func((2, 3, 5, 6, 4, 8, 9))
print(result)

[25, 36, 64, 81]

def my_func(x):
    my_list = []
    for i in x:
        if i > 4:
            my_list.append(i ** 2)
    return my_list

result = my_func((2, 3, 5, 6, 4, 8, 9))
print(result)

Implement a function called my_func() that takes a single parameter x (a dictionary) and multiplies the number of elements in the dictionary with the largest key in the dictionary, also returning the result when the function is called.

result = my_func({1: 3, 2: 3, 4: 5, 5: 9, 6: 8, 3: 7, 7: 0})
print(result)

49

def my_func(x):
    return len(x) * sorted(x.keys())[-1]

result = my_func({1: 3, 2: 3, 4: 5, 5: 9, 6: 8, 3: 7, 7: 0})
print(result)

Implement a function called my_func() that takes a single positional parameter x and a default parameter y which is equal to 10 and multiplies the two, also returning the result when the function is called.

result = my_func(5)
print(result)

50

def my_func(x, y = 10):
    return x * y

result = my_func(5)
print(result)

Implement a function called my_func() that takes a single positional parameter x and two default parameters y and z which are equal to 100 and 200 respectively, and adds them together, also returning the result when the function is called.

result = my_func(50)
print(result)

350

def my_func(x, y = 100, z = 200):
    return x + y + z

result = my_func(50)
print(result)

Add the necessary line of code inside the function in order to get 80 as a result of calling myfunc() and have the result printed out to the screen.

var = 8
def my_func(x):
    print(x * var)
    var = 12

my_func(10)

80

var = 8
def my_func(x):
    global var
    print(x * var)
    var = 12

my_func(10)

Write code that will import only the pi variable from the math module and then it will format it in order to have only 4 digits after the floating point. Of course, print out the result to the screen using the print() function.

3.1416

from math import pi

print("%.4f" % pi)

Add the necessary code in between print’s parentheses in order to read the content of text_file.txt as a string and have the result printed out to the screen.

f = open("text_file.txt", "r")
print()

f = open("text_file.txt", "r")
print(f.read())

Add the necessary code in between print’s parentheses in order to read the content of text_file.txt as a list where each element of the list is a row in the file, and have the result printed out to the screen.

f = open("text_file.txt", "r")
print()

f = open("text_file.txt", "r")
print(f.readlines())

Add the necessary code on line 5 in order to bring back the cursor at the very beginning of text_file.txt before reading from the file once again.

f = open("text_file.txt", "r")
f.read()
print()

f = open("text_file.txt", "r")
f.read()
f.seek(0)
print(f.readlines())
