Exercise
1
Consider that you have a text file containing
lines of different lengths (you can create this file using a text
editor like NotePad and typing what you want inside).
Write a script that searches and displays the longest line.
Exercise 2
From
3 pre-existing text files A.txt, B.txt, C.txt
(you
can create these files yourself with BlocNote for ie. by putting a
few sentences into
them
and then saving them in .txt format), create
a
new D.txt file
that contains all the content of the 3 files.
Exercice 3
Suppose you have a text file containing names as the first column, amount of money in bank as second column, and interests rate (in%) as the third column, separated by a tabulation (« \t »), ig.:
Jean 3000 1.2
Bob 2500 1.4
Fred 2200 2.5
Write a script that displays the amount of money for each people after 10 years, considering the interests rate.
Some help :
* convert a string to a list :
L = my_string.split(« \t ») # here the separator is a tabulation (character « \t »)
* list to string (should not be needed, for this exercise) :
my_string = «\t ».join(L) # here the separator is a tabulation
More :
- The previous question (compute and display names + new amounts) should be coded as a function. Reuse this function to write the results into a text file.
