Đọc != is defined as not equal to operator. It returns True if operands on either side are not equal to each other, and returns False if they are equal. 

Bàn luận It is important to keep in mind that this comparison operator will return True if  the values are same but are of different data types.

Trong bài viết này, chúng ta sẽ thấy các toán tử! = (Không bằng). Trong Python! = Được định nghĩa là không bằng toán tử. Nó trả về true nếu các toán hạng ở hai bên không bằng nhau và trả về sai nếu chúng bằng nhau. & Nbsp;Value A != Value B

Lưu ý: Điều quan trọng là phải nhớ rằng toán tử so sánh này sẽ trả về true nếu & nbsp; các giá trị giống nhau nhưng thuộc các loại dữ liệu khác nhau.Comparing different values of the same data type

Python3

Cú pháp: Giá trị A! = Giá trị B

Ví dụ 1: So sánh các giá trị khác nhau của cùng loại dữ liệu

A =

x = 10
y = 10
z = 20

print(f'x is not equal to y = {x!=y}')

flag = x != z
print(f'x is not equal to z = {flag}')

# python is strongly typed language
s = '10'
print(f'x is not equal to s = {x!=s}')

x = 10
y = 10
z = 20

print(f'x is not equal to y = {x!=y}')

flag = x != z
print(f'x is not equal to z = {flag}')

# python is strongly typed language
s = '10'
print(f'x is not equal to s = {x!=s}')

x = 10
y = 10
z = 20

print(f'x is not equal to y = {x!=y}')

flag = x != z
print(f'x is not equal to z = {flag}')

# python is strongly typed language
s = '10'
print(f'x is not equal to s = {x!=s}')

#Use of operator not equal to
a= "3"
b= "4"
c = "4"
#If a is not equal to b then conditon will print true
print("a=",a,"b=",b,"\nResult of Not Equal to Operator is ",a!=b)
print("\n")
#if c equal to b then condition will print false as we are using not equal to operator
print(" b=",b,"c=",c,"\nResult of Not Equal to Operator is  ",b!=c)
print("\n")

x = 10
y = 10
z = 20

print(f'x is not equal to y = {x!=y}')

flag = x != z
print(f'x is not equal to z = {flag}')

# python is strongly typed language
s = '10'
print(f'x is not equal to s = {x!=s}')

#Use of operator not equal to
a= "3"
b= "4"
c = "4"
#If a is not equal to b then conditon will print true
print("a=",a,"b=",b,"\nResult of Not Equal to Operator is ",a!=b)
print("\n")
#if c equal to b then condition will print false as we are using not equal to operator
print(" b=",b,"c=",c,"\nResult of Not Equal to Operator is  ",b!=c)
print("\n")

#Use of operator not equal to
a= "3"
b= "4"
c = "4"
#If a is not equal to b then conditon will print true
print("a=",a,"b=",b,"\nResult of Not Equal to Operator is ",a!=b)
print("\n")
#if c equal to b then condition will print false as we are using not equal to operator
print(" b=",b,"c=",c,"\nResult of Not Equal to Operator is  ",b!=c)
print("\n")

Output:

True
False

Ví dụ 2: So sánh cùng các giá trị của loại dữ liệu khác nhau__ne__() gets called whenever the not equal operator is used. We can override this function to alter the nature of the not equal operator.

__Ne __ () được gọi bất cứ khi nào người vận hành không bằng nhau được sử dụng. Chúng ta có thể ghi đè chức năng này để thay đổi bản chất của toán tử không bằng nhau.
