b=['trek','cannondale','redline','specialized']
print(b)
['trek', 'cannondale', 'redline', 'specialized']
b=['trek','cannondale','redline','specialized']
print(b[0])
trek
b=['trek','cannondale','redline','specialized']
print(b[1])
print(b[-1])
cannondale
specialized
b=['trek','cannondale','redline','specialized']
messge = "my name is "+b[0]+'.'
print(messge)
my name is trek.
b=['trek','cannondale','redline','specialized']
print(b)
b[0]='dau'
print(b)
['trek', 'cannondale', 'redline', 'specialized']
['dau', 'cannondale', 'redline', 'specialized']
1.在列表末尾處新增元素b=['trek','cannondale','redline','specialized']
print(b)
print(b)
['trek', 'cannondale', 'redline', 'specialized']
['trek', 'cannondale', 'redline', 'specialized', 'cat']
下來呢,我們建立乙個空列表,再在其中新增元素『honda』,『woo』,『hod』
a=
print(a) #輸出最終的結果
['honda', 'woo', 'hod']
2.在列表中插入元素b=['trek','cannondale','redline','specialized']
b.insert(1,'pig')##在索引1出新增空間,並將值『pig』儲存到這個地方
print(b)
['trek', 'pig', 'cannondale', 'redline', 'specialized']
1.使用del語句刪除元素b=['trek','cannondale','redline','specialized']
print(b)
del b[0]##刪除了b中第乙個元素『trek』
print(b)
['trek', 'cannondale', 'redline', 'specialized']
['cannondale', 'redline', 'specialized']
2. 使用pop方法刪除元素b=['trek','cannondale','redline','specialized']
print(b)
popped_b=b.pop()
print(b)
print(popped_b)
['trek', 'cannondale', 'redline', 'specialized']
['trek', 'cannondale', 'redline']
specialized
b=['trek','cannondale','redline','specialized']
led_b = b.pop()
print("the last was " + led_b + '.')
the last was specialized.
3. 彈出列表中任何位置處的元素b=['trek','cannondale','redline','specialized']
first_b = b.pop(1)
print("i owned was a " + first_b + '.')
i owned was a cannondale.
4. 根據值刪除元素b=['trek','cannondale','redline','specialized']
print(b)
b.remove('redline')
print(b)
['trek', 'cannondale', 'redline', 'specialized']
['trek', 'cannondale', 'specialized']
b=['trek','cannondale','redline','specialized']
print(b)
tee = 'redline'
b.remove(tee)
print(b)
print("\nthe " + tee + " is too big to me. ")
['trek', 'cannondale', 'redline', 'specialized']
['trek', 'cannondale', 'specialized']
the redline is too big to me.
b=['trek','cannondale','redline','specialized']
b.sort()
print(b)
['cannondale', 'redline', 'specialized', 'trek']
b=['trek','cannondale','redline','specialized']
b.sort(reverse = true)
print(b)
['trek', 'specialized', 'redline', 'cannondale']
cars = ['bmw','audi','toyota','jeep']
print("here is the original list: ")
print(cars)
print("\nhere is the sorted list:")
print(sorted(cars))
print("\nhere is the original list again:")
print(cars)
here is the original list:
['bmw', 'audi', 'toyota', 'jeep']
here is the sorted list:
['jeep', 'audi', 'bmw', 'toyota']
here is the original list again:
['bmw', 'audi', 'toyota', 'jeep']
cars = ['bmw','audi','toyota','jeep']
print(cars)
cars.reverse()
print(cars)
['bmw', 'audi', 'toyota', 'jeep']
['jeep', 'toyota', 'audi', 'bmw']
cars = ['bmw','audi','toyota','jeep']
len(cars)

1.新增操作 生成乙個新的列表 extend 接受引數並將該引數的每個元素都新增到原有的列表中,原地修改列表而不是新建列表 insert 插入任意物件到列表中,可以控制插入位置。2.修改 修改列表本身只需要直接賦值操作就行。3.刪除操作 del 我們通過索引刪除指定位置的元素。remove 移除列表...
