+# List Comprehensions
+list comprehensions jsou super.
+Dovolujou zkratit kod uplne strasne moc.
+
+Je to prakticky `for` kterej dovoluje filtrovat.
+
+Tohle:
+```python
+# chceme sebrat vsechna sudo cisla do 1000
+n = []
+for i in range(1000):
+	if i % 2 == 0:
+		n.append(i)
+print(n)
+```
+Je ekvivalence:
+```python
+n = [i for i in range(1000) if i % 2 == 0]
+print(n)
+```
+coz muzeme cist jako: "n je seznam vsech cisel do 1000 kde zbytek z deleni dvemi je nula, tl;dr vsech sudych cisel"
