You can concatenate (combine) strings in Python using the plus sign.
Consider the following example:
name = 'Mike' surname = 'Tyson' full_name = name + surname print(full_name) >>> MikeTyson >>>
In the output above you can see that I’ve stored the name and surname into two separate variables. I’ve then used the + sign to combine them into a single variable (full_name) which was then printed on the screen. However, the text was combined without a space in between (MikeTyson). You can insert a space like this:
full_name = name + " " + surname >>> Mike Tyson >>>
In the example above I’ve combined the name variable, a space, and the surname variable.
Consider another example of concatenation:
age = 30 print('You are ' + age + ' years old.')
The code above will produce an error:
Traceback (most recent call last): File "strings.py", line 12, in <module> print ('You are ' + age + 'years old.') TypeError: must be str, not int
The TypeError occured because I’ve tried to combine an integer value (30) with a string. We need to explicitly specify that we want Python to use the integer as a string of characters. We can do this by using the str() function:
age = 30 print ('You are ' + str(age) + ' years old.') >>> You are 30 years old. >>>
Notice also how I’ve left a space behind are and before years, so that the output would be displayed correctly.
