Python: Convert string element to integer inside a given tuple using lambda
Python Lambda: Exercise-45 with Solution
Write a Python program to convert string element to integer inside a given tuple using lambda.
Sample Solution:
Python Code :
def tuple_int_str(tuple_str):
result = tuple(map(lambda x: (int(x[0]), int(x[2])), tuple_str))
return result
tuple_str = (('233', 'ABCD', '33'), ('1416', 'EFGH', '55'), ('2345', 'WERT', '34'))
print("Original tuple values:")
print(tuple_str)
print("\nNew tuple values:")
print(tuple_int_str(tuple_str))
Sample Output:
Original tuple values: (('233', 'ABCD', '33'), ('1416', 'EFGH', '55'), ('2345', 'WERT', '34')) New tuple values: ((233, 33), (1416, 55), (2345, 34))

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
