Python元组练习
在这里，我们将介绍以下Python元组练习，
创建和打印元组
将元组解包成字符串
创建一个包含字符串字母的元组
创建一个元组，其中包含字符串的首字母，但不包含首字母
反转元组
考虑以下程序，它包含所有上述练习。
'''
1) Creating & printing a tuple
'''
cities = ("New Delhi", "Mumbai", "Indore")
print("cities: ", cities)
print("cities[0]: ", cities[0])
print("cities[1]: ", cities[1])
print("cities[2]: ", cities[2])
print() #打印换行符
'''
2) Unpacking the tuple into strings
'''
str1, str2, str3 = cities
print("str1: ", str1)
print("str2: ", str2)
print("str3: ", str3)
print() #打印换行符
'''
3) Create a tuple containing the letters
of a string
'''
tpl = tuple("Hello")
print("tpl: ", tpl)
print() #打印换行符
'''
4) Creating a tuple containing all but the
first letter of a string
'''
#通过直接字符串
tpl1 = tuple("Hello"[1:])
print("tpl1: ", tpl1)
#通过字符串变量
string = "Hello"
tpl2 = tuple(string[1:])
print("tpl2: ", tpl2)
print() #打印换行符
'''
5) Reversing a tuple
'''
name = ("Shivang", "Radib", "Preeti")
#使用切片技术
rev_name = name[::-1]
print("name: ", name)
print("rev_name: ", rev_name)输出结果
cities: ('New Delhi', 'Mumbai', 'Indore')
cities[0]: New Delhi
cities[1]: Mumbai
cities[2]: Indore
str1: New Delhi
str2: Mumbai
str3: Indore
tpl: ('H', 'e', 'l', 'l', 'o')
tpl1: ('e', 'l', 'l', 'o')
tpl2: ('e', 'l', 'l', 'o')
name: ('Shivang', 'Radib', 'Preeti')
rev_name: ('Preeti', 'Radib', 'Shivang')
