String formatting is like String interpolation. It is the process of displaying variables in predefined text. You can use it to insert a title in a graph, show a message or an error, or pass a statement to a function. 


The string value is passed to data. We are using HTML code to pass the string. It is mentioned by {} this symbol with name. So we can reuse the string or data for any method.str.format() method in Python is used for variable substitutions and value formatting. Positional formatting, this lets you concatenate elements together within a string. 

The __name__ is a built-in variable that executes the current module's name. The interpreter sets the __name__ variable to have a value “__main__”, if the source file is executed as the main program. If this file is imported from another module, the __name__ will be set to the module's name. We must declare the value of num and name. This value is passed into the Flask string. The app route is getting data from this string. 


Here is an example of how to pass a string using Flask:

Preview of the output that you will get on running this code from your IDE.

Code

In this solution we used flask library of python.

Dependent Libraries : 
app = Flask(__name__)

num = 55
name = 'Jon Smith'

string = f'{name} Employee ID {num}'
print(string)
@app.route('/')
def get_data():
    return '''<?xml version="1.0" encoding="UTF-8"?>
<person>
    <name> {string} </name>
</person>
'''.format(string=string)


if __name__ == '__main__':
    app.run(debug=True, port=5000)

Instructions

Follow the steps carefully to get the output easily.

  1. Download and Install the PyCharm Community Edition on your desktop.
  2. Install flask on your IDE from python interpreter in setting options.
  3. Create new python file on your IDE.
  4. Copy the snippet using the 'copy' button and paste it in your python file.
  5. Import flask
  6. Run the current file to generate the output.


I hope you found this useful. I have added the link to dependent library, version information in the following sections.


I found this code snippet by searching for ' Flask pass string ' in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. PyCharm Community Edition 2022.3.1
  2. The solution is created in Python 3.11.1 Version
  3. flask 2.2.2 Version


Using this solution, we can do flask pass string.This process also facilities an easy to use, hassle free method to create a hands-on working version of code in python which would help us to do flask pass string.
