Here, we are covering following Python tuple exercises,

在这里，我们将介绍以下Python元组练习 ，

1. Creating & printing a tuple

   创建和打印元组

2. Unpacking the tuple into strings

   将元组解包成字符串

3. Create a tuple containing the letters of a string

   创建一个包含字符串字母的元组

4. Creating a tuple containing all but the first letter of a string

   创建一个元组，其中包含字符串的除首字母外的所有字母

5. Reversing a tuple

   反转元组

Consider the following program, it contains all above-mentioned exercises.

考虑以下程序，其中包含所有上述练习。

'''
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() # prints a newline
'''
2) Unpacking the tuple into strings
'''
str1, str2, str3 = cities
print("str1: ", str1)
print("str2: ", str2)
print("str3: ", str3)
print() # prints a newline
'''
3) Create a tuple containing the letters 
of a string
'''
tpl = tuple("Hello")
print("tpl: ", tpl)
print() # prints a newline
'''
4) Creating a tuple containing all but the 
first letter of a string
'''  
# by direct string
tpl1 = tuple("Hello"[1:])
print("tpl1: ", tpl1)
# by string variables
string = "Hello"
tpl2 = tuple(string[1:])
print("tpl2: ", tpl2)
print() # prints a newline
'''
5) Reversing a tuple
'''
name = ("Shivang", "Radib", "Preeti")
# using slicing technique
rev_name = name[::-1]
print("name: ", name)
print("rev_name: ", rev_name)

Output

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')
