How do you add a string to a value in python?
\(\newcommand{L}[1]{\| #1 \|}\newcommand{VL}[1]{\L{ \vec{#1} }}\newcommand{R}[1]{\operatorname{Re}\,(#1)}\newcommand{I}[1]{\operatorname{Im}\, (#1)}\) Show Option 1 - the string format method¶You can use the
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 add a string to a variable 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 add a string to a number in Python?In Python, we normally perform string concatenation using the + operator. The + operator, however as we know, is also used to add integers or floating-point numbers.
How do you add a string to a value?Concatenating Strings. Using the "+" operator − Java Provides a concatenation operator using this, you can directly add two String literals.. Using the concat() method − The concat() method of the String class accepts a String value, adds it to the current String and returns the concatenated value.. How do you add two strings to a value in Python?Two strings can be concatenated in Python by simply using the '+' operator between them. More than two strings can be concatenated using '+' operator.
