 ### Tuples (immutable)
 
-    tuple = ()
+```py
+tuple = ()
+```
 
 ### Lists (mutable)
 
-    list = []
-    list[i:j]  # returns list subset
-    list[-1]   # returns last element
-    list[:-1]  # returns all but the last element
-    *list      # expands all elements in place
-
-    list[i] = val
-    list[i:j] = otherlist  # replace ith to jth-1 elements with otherlist
-    del list[i:j]
-
-    list.append(item)
-    list.extend(another_list)
-    list.insert(index, item)
-    list.pop()        # returns and removes last element from the list
-    list.pop(i)       # returns and removes i-th element from the list
-    list.remove(i)    # removes the first item from the list whose value is i
-    list1 + list2     # combine two list    
-    set(list)         # remove duplicate elements from a list
-
-    list.reverse()    # reverses the elements of the list in-place
-    list.count(item)
-    sum(list)
-
-    zip(list1, list2)  # returns list of tuples with n-th element of both list1 and list2
-    list.sort()        # sorts in-place, returns None
-    sorted(list)       # returns sorted copy of list
-    ",".join(list)     # returns a string with list elements seperated by comma

 ### Dict
 
-    dict = {}
-    dict.keys()
-    dict.values()
-    "key" in dict    # let's say this returns False, then...
-    dict["key"]      # ...this raises KeyError
-    dict.get("key")  # ...this returns None
-    dict.setdefault("key", 1)
-    **dict           # expands all k/v pairs in place
+```py
+dict = {}
+dict.keys()

+```
 
 ### Iteration
 
-    for item in ["a", "b", "c"]:
-    for i in range(4):        # 0 to 3
-    for i in range(4, 8):     # 4 to 7
-    for i in range(1, 9, 2):  # 1, 3, 5, 7
-    for key, val in dict.items():
-    for index, item in enumerate(list):
+```py
+for item in ["a", "b", "c"]:
+for i in range(4):        # 0 to 3
+for i in range(4, 8):     # 4 to 7
+for i in range(1, 9, 2):  # 1, 3, 5, 7

 ### Casting
 
-    int(str)
-    float(str)
-    str(int)
-    str(float)
-    'string'.encode()
+```py
+int(str)
+float(str)
+str(int)
+str(float)
+'string'.encode()
+```
 
 ### Comprehensions
 
-    [fn(i) for i in list]            # .map
-    map(fn, list)                    # .map, returns iterator
-
-    filter(fn, list)                 # .filter, returns iterator
-    [fn(i) for i in list if i > 0]   # .filter.map
+```py
+[fn(i) for i in list]            # .map
+map(fn, list)                    # .map, returns iterator
+
+filter(fn, list)                 # .filter, returns iterator
+[fn(i) for i in list if i > 0]   # .filter.map
+```
 
 ### Regex
 
-    import re
+```py
+import re
 
-    re.match(r'^[aeiou]', str)
-    re.sub(r'^[aeiou]', '?', str)
-    re.sub(r'(xyz)', r'\1', str)
+re.match(r'^[aeiou]', str)
+re.sub(r'^[aeiou]', '?', str)
+re.sub(r'(xyz)', r'\1', str)
 
-    expr = re.compile(r'^...$')
-    expr.match(...)
-    expr.sub(...)
+expr = re.compile(r'^...$')
+expr.match(...)
+expr.sub(...)
+```
