Listing 4-7. read(100) Reading in data line by line is so common that there is a method provided to do just that. In Listing 4-8, you can see how to read in a single line, or how to loop through the entire file. 29 CHAPTER 4 ■ FILES AND I/O Listing 4-8. readline() OR >>> for line in fd1: >>> do_my_process(line) If the file is not too large, you can read the entire contents into a list, where each element is a line from the file. Listing 4-9 provides an example. Listing 4-9. readlines() >>> first_line = file_list Writing a text file only requires a few minor changes.
Listing 2-16. time() 2-8. Calculating Date/Time Differences Problem You need to be able to find differences between two times and/or two dates. 17 CHAPTER 2 ■ NUMBERS, DATES, AND TIMES Solution Python provides the timedelta object as part of the datetime module. How It Works You can create a timedelta object that represents some date or time span. If you have two datetime objects, you can subtract them to get a timedelta object, as in Listing 2-17. Listing 2-17. 532031 If you want to create a fixed timedelta, say one week, that you want to add to a given datetime object, you can create it and use it as in Listing 2-18.
Solution You can apply a translation map to an entire string. This is handy if you want to accomplish several replacements. How It Works You can use the translate() method of your string to apply this mapping. While you could create the translation table manually, the string data type contains a helper function called maketrans() that creates a translation table that maps each character in the first parameter to the character at the same position in the second parameter. This is shown in Listing 1-19.
