+## The Infinite loop
+
+If a condition never becomes false, a loop will never end. Such a loop is called an infinite loop.
+
+The syntax of a while loop is:
+
+```
+while True:
+    print('loop step')
+```
+
+**_Instructions_**
+**Fix an infinite loop, the condition can become true.**

+## For
+
+For loops iterate over a given sequence
+
+```
+lst = [2, 3, 5]
+for i in lst:
+    print(i)
+```
+
+The function range() return an iterable object with behaves as if it is a list. The object is not a list, it returns the successive items of the desired sequence. 
+
+```
+for i in range(9):
+    print(i)
+```
+
+It is possible to let the range start at another number, or to specify a different increment.
+
+```
+for i in range(0, 9, 3):
+    print(i)
+```
+
+**_Instructions_**
+**Generate the sequence of numbers between 2 and 10 and specify an increment 3.**
+**Calculate the sum of numbers of this sequence.**
