Concatenation of strings in Python

To add (concatenate) strings, use the operator +:

pythontest = 'abc' + 'def' # add two lines
print(test) # 'abcdef'

Strings can also be stored in variables:

pythontest1 = 'abc'
test2 = 'def'

test3 = test1 + test2 # add two lines
print(test3) # 'abcdef'

You can also add variables and strings:

pythontest1 = 'abc'
test2 = 'def'

test3 = test1 + '!!!' + test2

print(test3)

Задание 1

Two lines are given:

Merge these lines into one new one and display it on the screen.

Задание 2

The following lines are given:

pythontxt1 = '12'
txt2 = '+'
txt3 = '5'

Задание 3

Change the solution to the previous problem so that after the merge, between the third and fourth lines there is an operator =.
