Remove tuples from list of tuples if greater than n in Python
When it is required to remove tuples from a list of tuples if it is greater than a value 'n', the lambda function can be used.
Anonymous function is a function which is defined without a name. In general, functions in Python are defined using 'def' keyword, but anonymous function is defined with the help of 'lambda' keyword.
It takes a single expression, but can take any number of arguments. It uses the expression and returns the result of it.
Below is a demonstration for the same −
Example
my_tuple = [('a', 130), ('b', 230), ('c', 25),('z', 654), ('f', 69)]
print("The list of tuple is : ")
print(my_tuple)
my_result = [i for i in my_tuple if i[1] >= 100]
print ("The resultant list of tuple is : ")
print(my_result)Output
The list of tuple is :
[('a', 130), ('b', 230), ('c', 25), ('z', 654), ('f', 69)]
The resultant list of tuple is :
[('a', 130), ('b', 230), ('z', 654)]Explanation
- A list of tuple is defined, and is displayed on the console.
- It is iterated over, and checked if any element is greater than or equal to zero.
- If yes, it is converted into a list.
- This operation's data is stored in a variable.
- This variable is the output that is displayed on the console.
