Python: Create a function that takes one argument multiplied with an unknown given number
Python Lambda: Exercise-2 with Solution
Write a Python program to create a function that takes one argument, and that argument will be multiplied with an unknown given number.
Sample Solution:
Python Code :
def func_compute(n):
return lambda x : x * n
result = func_compute(2)
print("Double the number of 15 =", result(15))
result = func_compute(3)
print("Triple the number of 15 =", result(15))
result = func_compute(4)
print("Quadruple the number of 15 =", result(15))
result = func_compute(5)
print("Quintuple the number 15 =", result(15))
Sample Output:
Double the number of 15 = 30 Triple the number of 15 = 45 Quadruple the number of 15 = 60 Quintuple the number 15 = 75

Previous: Write a Python program to create a lambda function that adds 15 to a given number passed in as an argument, also create a lambda function that multiplies argument x with argument y and print the result.
Next: Write a Python program to sort a list of tuples using Lambda.

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")
