Answer:
There is no difference between ‘’ and “” string type in python. Both are used to hold the string or sequence of character in the python. triple """ """ can also use for the same.
Example:
str1 = "aeiou"
str2 = 'aeiou'
str3 =""" hello"""
print(type(str1), type(str2),type(str3))
<class 'str'> <class 'str'> <class 'str'>
Here all are used to hold string or sequence of character.
A workflow consists of an orchestrated and repeatable pattern of business activity enabled by the systematic organization of resources into processes that transform materials, provide services, or process information.
Create a detailed outline of what you want to achieve and sketch a workflow diagram before using workflow chart software or templates. This will help to ensure your chart is accurate and complete. Always consider your process and workflow manageability when inserting logic in your workflow chart. You can use decision symbols, connectors and text boxes. Always confirm the accuracy of your workflow chart with other stakeholders.
