string method >>> shepherd = "Mary" >>> string_in_string = "Shepherd {} is on duty.".format(shepherd) >>> print(string_in_string) Shepherd Mary is on duty. The curly braces show where the inserted value should go. You can insert more than one value. The values do not have to be strings, they can be numbers and other Python objects. >>> shepherd = "Mary" >>> age = 32 >>> stuff_in_string = "Shepherd {} is {} years old.".format(shepherd, age) >>> print(stuff_in_string) Shepherd Mary is 32 years old. >>> 'Here is a {} floating point number'.format(3.33333) 'Here is a 3.33333 floating point number' You can do more complex formatting of numbers and strings using formatting options within the curly brackets — see the documentation on curly brace string formatting. This system allows us to give formatting instructions for things like numbers, by using a >>> print("Number {:03d} is here.".format(11)) Number 011 is here. This prints a floating point value ( >>> 'A formatted number - {:.4f}'.format(.2) 'A formatted number - 0.2000' See the Python string formatting documentation for more details and examples. Option 2 - f-strings in Python >= 3.6¶If you can depend on having Python >= version 3.6, then you have another attractive option, which is to use the new formatted string literal (f-string) syntax to insert variable values. An >>> shepherd = "Martha" >>> age = 34 >>> # Note f before first quote of string >>> stuff_in_string = f"Shepherd {shepherd} is {age} years old." >>> print(stuff_in_string) Shepherd Martha is 34 years old. Option 3 - old school % formatting¶There is an older method of string formatting
that uses the For Here is the example above, using >>> stuff_in_string = "Shepherd %s is %d years old." % (shepherd, age) >>> print(stuff_in_string) Shepherd Martha is 34 years old. How do you name a variable in a string in Python?String Into Variable Name in Python Using the vars() Function. Instead of using the locals() and the globals() function to convert a string to a variable name in python, we can also use the vars() function. The vars() function, when executed in the global scope, behaves just like the globals() function.
How do you add a name to a string in Python?You must use the + operator to append strings together. We can use the input function in Python to get your first and last name and then print your full name. A function can take input and returns some value.
How do you add string variables in Python?You can append another string to a string with the in-place operator, += . The string on the right is concatenated after the string variable on the left. If you want to add a string to the end of a string variable, use the += operator.
How do you assign a variable to a name in Python?Rules for Python variables:. A variable name must start with a letter or the underscore character.. A variable name cannot start with a number.. A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ ). Variable names are case-sensitive (age, Age and AGE are three different variables). |
