本篇文章是一篇关于输出元素的帖子
《Python for Beginners》为LearnStreet上的Python入门课程。本节要主学习内容为Lists and Tuples。
Lesson 6 Lists and Tuples
1. Length of List
盘算List变量的度长。
1 def run(var):
2 #return your code here
3 return len(var)
4
5 #This is just for you to see what happens when the function is called
6 print run([1,2,3,4,5])
输出结果:
5
2. Removing Elements of a List
移除表列中的某个元素。
days = ["funday","sunday","monday","tuesday","wednesday","thursday","friday"]
days.pop(0)
注意:pop(0)应用的是圆括号。
3. Appending Lists
在表列尾末加添元素。
days.append("saturday")
其中,days为List型类变量。
4. Concatenating Lists
连接两个表列。
1 def run(first, second):
2 #your code here
3 return first + second
4
5 #This is just for you to see what happens when the function is called
6 print run([1,2,3],[4,5,6])
1 def run():
2 #your code here
3 name = ("Guinevere", 9102)
4 return name
5
6 #This is just for you to see what happens when the function is called
7 print run()
输出结果:
('Guinevere', 9102)
6. 温习训练
1 # assume lst is a list and tup is a tuple
2 def run(lst, tup):
3 #your code here
4 if lst[1] == tup[1]:
5 return tuple(lst) == tup
6 else:
7 return "not equal"
8
9 #This is just for you to see what happens when the function is called
10 print run([1,2,3],(1,2,3))
