### Dict
|

|
||||
|
||||
### 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 key, val in dict.items():

### [String](https://docs.python.org/2/library/stdtypes.html#string-methods)
|
||||
|
||||
str[0:4]
|
||||
len(str)
|
||||
|
||||
string.replace("-", " ")
|
||||
",".join(list)
|
||||
"hi {0}".format('j')
|
||||
str.find(",")
|
||||
str.index(",") # same, but raises IndexError
|
||||
str.count(",")
|

### Casting
|

|
||||
int(str)
|
||||
float(str)
|
||||
|
||||
### Comprehensions
|
||||
|
||||
[fn(i) for i in list] # .map
|
||||
[fn(i) for i in list if i > 0] # .filter.map
|
||||
|
||||
### Regex
|
||||
|
||||
import regex
|
||||
|
||||
re.match(r'^[aeiou]', str)
|
||||
re.sub(r'^[aeiou]', '?', str)
|

re.sub(r'(xyz)', r'\1', str)
