list py code example

Example 1: creating a list in python

myList = [value,value,value] #note that you can use any amount of value
#you don not have to use value

Example 2: python list

#Creating lists
my_list = ['foo', 4, 5, 'bar', 0.4]
my_nested_list = ['foobar', ['baz', 'qux'], [0]]

#Accessing list values
my_list[2] # 5
my_list[-1] # 0.4
my_list[:2] # ['foo', 4, 5]
my_nested_list[2] # ['baz', 'quz']
my_nested_list[-1] # [0]
my_nested_list[1][1] # 'qux'

#Modifying lists
my_list.append(x) # append x to end of list
my_list.extend(iterable) # append all elements of iterable to list
my_list.insert(i, x) # insert x at index i
my_list.remove(x) # remove first occurance of x from list
my_list.pop([i]) # pop element at index i (defaults to end of list)
my_list.clear() # delete all elements from the list
my_list.index(x[, start[, end]]) # return index of element x
my_list.count(x) # return number of occurances of x in list
my_list.reverse() # reverse elements of list in-place (no return)
my_list.sort(key=None, reverse=False) # sort list in-place
my_list.copy() # return a shallow copy of the list

Example 3: python list

# example of list in python

myList = [9, 'hello', 2, 'python']

print(myList[0]) # output --> 9
print(myList[-3]) # output --> hello
print(myList[:3]) # output --> [9, 'hello', 2]
print(myList) # output --> [9, 'hello', 2, 'python']

Example 4: python list

#Creating lists
my_list = [1, "Hello", 3.4, 0, "World"]
my_nested_list = [['Hello', 'World'],[47,39]]

#Accessing lists
my_list[1] # Hello
my_list[-2] # 0
my_list[:3] # [1, "Hello", 3.4]
my_nested_list[1] #[47,39]
my_nested_list[0][1] # World

Example 5: python lists

fruits = ['apple', 'banana', 'mango', 'cherry']

for fruit in fruits:
  print(fruit)

Example 6: python list

# Create list
List = list()
List = []
List = [0, "any data type can be added to list", 25.12,
        ("Even tuples"), {"Dictionaries": "can also be added"},
       ["can", "be nested"]]
# Accessing items

List[1]		# 0
List[-1] 	# ["can", "be nested"]

# Operations
List.append(4)		# adds 4 to end
List.pop(n=-1)		# removes element from nth position
List.count(25.12)	# 1
