Have you ever entered a number into a Python program but received an error when trying to perform a calculation? This is a common problem for beginners. It often happens because the data type of a value is different from what the program expects. For example, when you use Python's input() function, the value entered by the user is returned as a string. If you want to perform mathematical calculations with that value, you may need to convert it into a numeric type first. This process is called type conversion . In this article, we will learn what type conversion is, why it is useful, how to convert values using int() , float() , str() , and bool() , and how to avoid common errors. 1. What Is Type Conversion in Python? Type conversion is the process of converting a value from one data type to another. For example, you may convert: A string into an integer. An integer into a floating-point number. A number into a string. A value into a Boolean value. Consider this example: number = ...
In the previous article, you learned how to combine branches using git merge . Merging preserves the complete branching history, which is useful because it shows exactly how development happened. However, sometimes developers prefer a cleaner and more linear commit history . Instead of creating a merge commit, Git provides another powerful command: git rebase The git rebase command takes the commits from one branch and replays them on top of another branch, making the project history appear as though the work happened in a straight line. Because git rebase rewrites commit history, it is a powerful command that should be used with care. In this article, you will learn: What git rebase is Why developers use rebase How rebase works Rebase vs Merge Interactive rebase Resolving conflicts during a rebase When to use rebase When to avoid rebase Best practices By the end of this article, you'll understand how rebase creates a cleaner project history and when it is appropriate to use it...
