How do you pass a string variable 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 pass a string value in Python?Program: # Python program to pass a string to the function # function definition: it will accept # a string parameter and print it def printMsg(str): # printing the parameter print str # Main code # function calls printMsg("Hello world!") printMsg("Hi! I am good.")
How do you declare a string variable in Python?To create a string, put the sequence of characters inside either single quotes, double quotes, or triple quotes and then assign it to a variable. You can look into how variables work in Python in the Python variables tutorial. For example, you can assign a character 'a' to a variable single_quote_character .
How do you pass variables in Python?If a Python newcomer wanted to know about passing by ref/val, then the takeaway from this answer is: 1- You can use the reference that a function receives as its arguments, to modify the 'outside' value of a variable, as long as you don't reassign the parameter to refer to a new object.
Can we pass string in function in Python?You can send any data types of argument to a function (string, number, list, dictionary etc.), and it will be treated as the same data type inside the function.
