1) Use the file object output to write the string "3.14159" to a file called pi.

2) A file named numbers.txt contains an unknown number of lines, each consisting of a single positive integer. Write some code that reads through the file and stores the largest number read in a variable named maxvalue.

3) A file named data1.txt contains an unknown number of lines, each consisting of a single integer. Write some code that creates a file named data2.txt and copies all the lines of data1.txt to data2.txt.

4) A file named data.txt contains an unknown number of lines, each consisting of a single integer. Write some code that creates two files, dataplus.txt and dataminus.txt, and copies all the lines of data1.txt that have positive integers to dataplus.txt, and all the lines of data1.txt that have negative integers to dataminus.txt. Zeros are not copied anywhere.

5) A file named numbers.txt contains an unknown number of lines, each consisting of a single positive integer. Write some code that reads through the file, ignoring those value that are not bigger than the maximum value read up to that point. The numbers that are NOT ignored are added, and their sum stored in a variable called runsum. For example, if the sequence of integers in the file were "9 7 5 18 13 2 22 16" the code would ignore: 7, 5, 13, 2 and 16; it would add 9, 18, and 22, storing their sum, 49, into runsum.
