Relational Operators

> ⇒ Greater-than
>= ⇒ Greater-than-equals
< ⇒ Less-than
<= ⇒ Less-than-equals

Example

Python

num1 = 10
num2 = 20

print("num1 > num2 is", num1>num2)
print("num1 >= num2 is", num1>=num2)
print("num1 < num2 is", num1<num2)
print("num1<=num2 is", num1<=num2)

Output

PowerShell

num1 > num2 is False
num1 >= num2 is False
num1 < num2 is True
num1<=num2 is True

We can apply relational operators for str types also.

Example

Python

str1 = "ajay"
str2 = "ajay"

print("str1 > str2 is", str1>str2)
print("str1 >= str2 is", str1>=str2)
print("str1 < str2 is", str1<str2)
print("str1<=str2 is", str1<=str2)

Output

PowerShell

str1 > str2 is False
str1 >= str2 is True
str1 < str2 is False
str1<=str2 is True

Example

Python

str1 = "D"
str2 = "d"

print(str1 < str2)

Output

PowerShell

True

We can apply relational operators for bool types also.

Example

Python

print(True > True)
print(True >= True)
print(10 > True)
print(False > True)

Output

PowerShell

False
True
True
False

We can not apply relational operators for different data types.

Example

Python

print(10>"ajay")

Output

PowerShell

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

Remark

Chaining of relational operators is possible. In the chaining, if all comparisons returns True then only result is True. If at least one comparison returns False then the result is False.

Python

print(10<20)
print(10<20<30)
print(10<20<30<40)
print(10<20<3050)

Output

PowerShell

True
True
True
True
