A. Create a variable containing a one row character array containing ‘some letters’. Do this using square brackets and individual characters. Use class to confirm the type of the variable.
B. Repeat the last part but create the string variable using a single set of single quotes.
C. Make a two row character array containing ‘some’ and ‘letters’ on separate rows. What do we need to do to make sure these two words can be fitted into a two row array?
D. Make an explicit conversion of the character array from the last part to a numeric type.
E. What happens if we try to make an explicit conversion of the character array of the last part to a logical type?
F. Make an implicit conversion of the character array to a numeric type.
G. For each of the following string, try and generate a corresponding numeric value using the str2double function. Give the reason why some of these conversions can fail and how we can test for it.
‘-4’
‘j’
‘2.5’
‘X.9’

- 1. Write a Python regex pattern that matches a valid email address, assuming that an email address consists of a username, followed by the "@" symbol, followed by a domain name, which in turn consists of one or more subdomains separated by dots, and ending with a top-level domain (e.g., .com, .org, .edu, etc.). 2. Using the re.findall() function in Python, write a Python code snippet that takes the text string and the regex pattern from Q4 and returns a list of all the email addresses found in the string. 3. Suppose you want to modify the regex pattern from Q4 to also match email addresses that contain hyphens ("-") in the username and/or domain name. What changes would you make to the pattern, and why? 4. Using the modified regex pattern from Q6, write a Python code snippet that takes the text string and the modified regex pattern, and returns a list of all the email addresses found in the string. Note: You can assume that the text string contains valid email addresses separated by…continue this already existing code to complete the problem in the pictureHi. I need help.
