100 Days of Code: Python Developer Challenge 2023 | Day 7

Hi guys.

We have completed the sixth day of the challenge. To repeat or revise the sixth day:

100 Days of Code: Python Developer Challenge 2023 | Day 6

100 Days of Code: Python Developer Challenge 2023 | Day 7

Let’s start the exercises on the seventh day!

Exercise1:

The following codes are given:

• code1 = ‘Python3.3.11’
• code2 = ‘PythonLoVe_U’
• code3 = ‘P-y-t-h-o-n’
• code4 = ‘Python3LoveU’

Using the appropriate method, check whether the codes consist only of alphanumeric characters (numbers + letters). Print the result to the consol.

code1 = 'Python3.3.11'
code2 = 'PythonLoVe_U'
code3 = 'P-y-t-h-o-n'
code4 = 'Python3LoveU'
 
 
print(f'code1: {code1.isalnum()}')
print(f'code2: {code2.isalnum()}')
print(f'code3: {code3.isalnum()}')
print(f'code4: {code4.isalnum()}')

If we run this code, we will see the following output:

code1: False

code2: False

code3: False

code4: True

Exercise2:

The following text is given:

• text = ‘100 Days of Code: Python Developer Challenge 2023 | Day 7’

Using the appropriate method convert all letters to lowercase. Print the result to the console.

text = '100 Days of Code: Python Developer Challenge 2023 | Day 7'
 
 
print(text.lower())

If we run this code, we will see the following output:

100 days of code: python developer challenge 2023 | day 7

Exercise3:

The following text is given:

• text = ‘100-Days-of-Code:-Python-Developer-Challenge-2023 | Day-7‘

Using the appropriate method replace the dashes with a space. Print the result to the console.

text = '100-Days-of-Code:-Python-Developer-Challenge-2023 | Day-7'

print(text.replace('-', ' '))

If we run this code, we will see the following output:

100 Days of Code: Python Developer Challenge 2023 | Day 7
