Storing text
You've already met with strings in the very first exercises. String - is simply a text which can contain letters, symbols, numbers, and so on. The one requirement - is to put your text inside quotes 'text' or "text" or '''text'''. The number of quotes on the left side must be equal to the number of quotes on the right side.
To convert a variable into a string use the str function or place your text inside quotes. It's useful if you, for example, need to make Python understand that 3 is string, not number (by default, Python will assign 3 as int).
For example, let's create a string with only the number 23
# first way to create string string1 = '23' print(type(string1)) # second way to create string string2 = 23 print(type(string2)) # convert it into string type string2 = str(string2) print(type(string2))

Given a math expression assigned to variables expr1 and expr2. Not changing expr1, convert expr2 by using quotes, and print its value.
