When it is required to remove the strings froma tuple, the list comprehension and the 'type' method can be used.
A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on).
A list of tuple basically contains tuples enclosed in a list.
The list comprehension is a shorthand to iterate through the list and perform operations on it.
The 'type' method returns the class of the iterable passed to it as an argument.
Below is a demonstration for the same −
Example
my_list = [('Hi', 45, 67), ('There', 45, 32), ('Jane', 59, 13)]
print("The list is : ")
print(my_list)
my_result = [tuple([j for j in i if type(j) != str])
for i in my_list]
print("The list of tuple after removing the string is : ")
print(my_result)Output
The list is :
[('Hi', 45, 67), ('There', 45, 32), ('Jane', 59, 13)]
The list of tuple after removing the string is :
[(45, 67), (45, 32), (59, 13)]Explanation
- A list of tuple is defined, and is displayed on the console.
- It is iterated over, using list comprehension.
- It is checked to see for not being a string.
- It is then converted to a tuple, and then to a list again.
- This operation's data is stored in a variable.
- This variable is the output that is displayed on the console.
