【人工智能】python学习路上一发不可收拾

没想到python真的那么简单，前几节陆续练习了python编辑工具的破解，python的打印语句，python的变量，python的常用函数 type() ,str() ,len()，python的运算符，还有python的字符串。真的是真正意义上的从0开始动手练习python、其实真实的学习就是这么一个过程，下面进一步练习，这一节练习python的列表操作。一直练习下午，是为了到时候编写训练人工智能模型神经网络

### Lists ###

# Definición

my_list = list()
my_other_list = []

print(len(my_list))

my_list = [35, 24, 62, 52, 30, 30, 17]

print(my_list)
print(len(my_list))

my_other_list = [35, 1.77, "Brais", "Moure"]

print(type(my_list))
print(type(my_other_list))

# Acceso a elementos y búsqueda

print(my_other_list[0])
print(my_other_list[1])
print(my_other_list[-1])
print(my_other_list[-4])
print(my_list.count(30))
# print(my_other_list[4]) IndexError
# print(my_other_list[-5]) IndexError

print(my_other_list.index("Brais"))

age, height, name, surname = my_other_list
print(name)

name, height, age, surname = my_other_list[2], my_other_list[1], my_other_list[0], my_other_list[3]
print(age)

# Concatenación

print(my_list + my_other_list)
#print(my_list - my_other_list)

# Creación, inserción, actualización y eliminación

my_other_list.append("MoureDev")
print(my_other_list)

my_other_list.insert(1, "Rojo")
print(my_other_list)

my_other_list[1] = "Azul"
print(my_other_list)

my_other_list.remove("Azul")
print(my_other_list)

my_list.remove(30)
print(my_list)

print(my_list.pop())
print(my_list)

my_pop_element = my_list.pop(2)
print(my_pop_element)
print(my_list)

del my_list[2]
print(my_list)

# Operaciones con listas

my_new_list = my_list.copy()

my_list.clear()
print(my_list)
print(my_new_list)

my_new_list.reverse()
print(my_new_list)

my_new_list.sort()
print(my_new_list)

# Sublistas

print(my_new_list[1:3])

# Cambio de tipo

my_list = "Hola Python"
print(my_list)
print(type(my_list))

 我们来运行代码

运行没问题，我们来分析每一行代码

声明一个空的列表变量

my_list = list()

或者这种方式，这应该也是一个数组

my_other_list = []

打印出列表的长度

print(len(my_list))

数组赋值

my_list = [35, 24, 62, 52, 30, 30, 17]

打印数组和数组长度

print(my_list)
print(len(my_list))

数组列表里赋不同类型的值

my_other_list = [35, 1.77, "Brais", "Moure"]

打印看看变量数组的类型

print(type(my_list))
print(type(my_other_list))

遍历数组下标

print(my_other_list[0])
print(my_other_list[1])
print(my_other_list[-1])
print(my_other_list[-4])

 数组的添加元素，删除元素一系列操作

my_other_list.append("MoureDev")
print(my_other_list)

my_other_list.insert(1, "Rojo")
print(my_other_list)

my_other_list[1] = "Azul"
print(my_other_list)

my_other_list.remove("Azul")
print(my_other_list)

my_list.remove(30)
print(my_list)

print(my_list.pop())
print(my_list)

my_pop_element = my_list.pop(2)
print(my_pop_element)
print(my_list)
