Unpacking Tuples in Python

In Python there is a possibility to do unpacking tuples - assign a separate variable to each element. To do this, the variables are listed on the left side of the expression, and the tuple we need is indicated on the right side:

pythontpl = ('a', 'b', 'c')
txt1, txt2, txt3 = tpl

print(txt1) # 'a'
print(txt2) # 'b'
print(txt3) # 'c'

But there is an important nuance here - the number of variables must match the number of elements in the tuple. Otherwise, an error will be returned:

pythontpl = ('a', 'b', 'c')
txt1, txt2 = tpl

print(txt1) # will display an error

pythontpl = ('john', 'smit')

pythontpl = (2, 6, 14)
