Python Exercise: Unpack a tuple in several variables
4. Unpack a Tuple into Several Variables
Write a Python program to unpack a tuple into several variables.
Sample Solution:
Python Code:
# Create a tuple containing three numbers
tuplex = 4, 8, 3
# Print the contents of the 'tuplex' tuple
print(tuplex)
# Unpack the values from the tuple into the variables n1, n2, and n3
n1, n2, n3 = tuplex
# Calculate and print the sum of n1, n2, and n3
print(n1 + n2 + n3)
# Attempt to unpack the tuple into more variables (n1, n2, n3, and n4)
# This will raise a "ValueError" since there are not enough values in the tuple to unpack into all the variables
n1, n2, n3, n4 = tuplex
Sample Output:
(4, 8, 3)
15
Traceback (most recent call last):
File "32fd05c0-3096-11e7-a6a0-0b37d4d0b2c6.py", line 8, in <module>
n1, n2, n3, n4 = tuplex
ValueError: not enough values to unpack (expected 4, got 3)
