ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"Install Python3
brew install python3Declare directly with variable name
abc = 'some string'It is also called array in some languages. String and numbers (Any Type) are allowed to store within the list.
list_var = ['some thing', 123, 'another thing']
list_var.append('new item') //append new item
list_var.pop() //pop the last item
list_var.pop(0) //index of the item
len(list_var) //get length of arrayIt is similar to Objective-C Dictionary, with key-value opinion. However its key can be integer value while it is not allowed in some other languages. It can store a pointer within the value too
Car = {'seats': ['driver', 'passanger'], 'mirror': 'front', 1234: 'others'}
Car[1234] //others
Car['mirror'] //front
Car['door'] = 4 //add new or edit keyIt is a data structure (such as choices), not really everyone will like this.
Tup = (123, 234)
Tup = (('another', 'another'), ('some', 'some'))Special thing to note
tup = (('tic', 'tic'), ('tac', 'tac'))
tup += ('toe', 'toe')(('tic', 'tic'), ('tac', 'tac'), 'toe', 'toe')
To append ('toe', 'toe') in tail
tup = (('tic', 'tic'), ('tac', 'tac'))
tup += (('toe', 'toe'),)(('tic', 'tic'), ('tac', 'tac'), ('toe', 'toe'))
Use : to start the loop, and indention will be loop scope Leave a empty line to state the end of loop (Other kind of indention will do)
bag = [10, 11, 12, 13]
for item in bag:
print(item)i = 1
while i < 11:
print(i)
i = i + 1Boolean value
obj_a = True
obj_b = False
obj_a == obj_b //False
obj_a is obj_b //False
not obj_a is obj_b //Truelist_d = ['Justin', 123, 'Apple', 'Food']
for item in list_d:
if isinstance(item, str):
print(item)using sort or sorted function
str_items = ['aaa', 'Abc', 'AD', 'ED', 'JM']
str_items.sort()
str_items.sort(key=str.lower)
str_items.sort(key=str.lower, reverse=True)
new_items = sorted(sort_items)
new_itmes = sorted(str_items, key=str.lower, reverse=True)note: There is different between Python2 and Python3
int_items = [1313, 21938.3, 12.23, 1314]
sum(int_items)
len(int_items)
total = sum(int_items)
average = sum(int_items)/len(int_items)
average = 1114124/len(int_items)
