1. Create a Python source file named "ex2.py" that will include the following two lines. Be sure to replace [YourNameHere] with your full name. \# Student: YourNameHere \# Programming Exercise: 2_1 2. Next to the above two lines, write Python codes that imports both "InputBox.py" and "MessageBox.py". Then display a dialog box to ask the user to enter how much pounds she/he weights in pounds, convert the value to kilograms, and then display the result as a string similar to "You weight xxx.xxxx kg." in a message box, as shown below. [Hint: 1 pound is equal to 0.45359237 kilogram.] rlg. ex 2 3. Download the "programming exercise template", and then rename it to ex2.doc. Copy and paste the source code to the template. Capture a screen shot similar to Fig. ex2 and paste it to a Microsoft Word document named ex2.doc (or ex2.docx). [Feel free to convert the Word document to a .pdf file.]
