single value Tuple in python

If we indicate the parenthesis with single value  then that should not be considered as tuple .

example 1:

t=(10)
print(type(t))
print(t)

output:
<class 'int'>
10

example 2:
t=('A')
print(type(t))

print(t)

output:
<class 'str'>
A

single value tuple indicates as (first value,)

example 3:
t=(10)
print(type(t))
print(t)
t=('A')
print(type(t))
print(t)
t=(10,)
print(type(t))

print(t)

output:
<class 'int'>
10
<class 'str'>
A
<class 'tuple'>
(10,)

slice operator using list

list we can copy  by using slice operator  ,the element of the first  list should same in the next list but when you change the element from the cloned list  that elements only changes previous list should same like before.

x=[10,20,30,40]
y=x[:]
print(x)
y[1]=111
print(id(x))
print(id(y))
print(y)
print(x)

2576163860680
[10, 111, 30, 40]
[10, 20, 30, 40]

list alias in python

In the list we can make many alias for the single list

x1 = [5, 8, 10, 16, 20]
y=x1
print(x1)
print(y)
print(id(x1))
print(id(y))

output:
[5, 8, 10, 16, 20]

output:

[5, 8, 10, 16, 20]
[20, 16, 10, 8, 5]

example:
if reverse is false then it will give normal sorting order only
a1=[20,5,16,10,8]
a1.sort()
print(a1)
a1.sort(reverse=True)
print(a1)
a1.sort(reverse=False)
print(a1)

output:

sort method in python

a1=[30,5,14,8,0]
a1.sort()
print(a1)

output:
[0, 5, 8, 14, 30]

example2:

a1=[30,5,14,8,0]
a1.sort()
print(a1)
a2=["bat","ant","dog","cat"]
a2.sort()
print(a2)

output:
[0, 5, 8, 14, 30]
['ant', 'bat', 'cat', 'dog']

example3:
if upper case strings and lowercase strings are present then it will shows the uppercase string first then it will shows the lower case strings

a1=[30,5,14,8,0]
a1.sort()
print(a1)
a2=["Bat","ant","Dog","Cat"]
a2.sort()
print(a2)

output:
[0, 5, 8, 14, 30]
['Bat', 'Cat', 'Dog', 'ant']

example 4:
strings and integers with in list then they will not sorted .compiler will shows the error

a1=[10,'B',20,'C',4,'A']
a1.sort()
print(a1)

output:

TypeError: '<' not supported between instances of 'str' and 'int'
