Stuck on how to complete my code as I keep getting errors. Here are the instructions and my code so far. Please answer in Python. Thank you. • Replace the user-specified number of messages to be sent with a variable numMsgs that youcan define internally in your program. We will set numMsgs according to the experimentsspecified below.• Replace the user-specified message string with a string of the size defined by theexperiments below. Please utilize the following example that allows us to create a stringcomprising of null values of a size specified using the variable numBytes.In the following example, we are creating a string called message of a 1000 bytes. We cansimilarly create a message string of 5000 and 10000 Bytes by changing the value ofnumBytes.numBytes = 1000message = ‘\x00’ * numBytesTo get the size of this message (needed later as a part of your code output), you may use thegetsizeof utility from the system library in Python. Please import the system library as ‘importsys’.…
Code in Python mystr is "numberlike" if: - mystr is not the empty string - the first character in mystr is a digit - the count of '.' in mystr is zero or one (can't have more than one decimal point in a number) - every character in mystr is a digit ('0', '1', '2', ..., '9') or a decimal point ('.') Write the code to define the function is_numberlike(mystr), which takes a string parameter and returns a boolean result. If mystr is numberlike, the function returns True; otherwise, the function returns False. Hint: Check the first three requirements with decision statements, then use a for loop to iterate over mystr and check the every character is a digit or a dot For example: Test Result if not (is_numberlike("13.5") is True): print("error") if not (is_numberlike("-5532") is False): print("error") if not (is_numberlike("175") is True): print("error")
