This paper provides an in-depth analysis of the common TypeError: 'numpy.float64' object cannot be interpreted as an integer in Python programming, which typically occurs when using NumPy arrays for loop control. Through a specific code example, the article explains the cause of the error: the range() function expects integer arguments, but NumPy floating-point operations (e.g., division) return numpy.float64 types, leading to type mismatch. The core solution is to explicitly convert floating-point numbers to integers, such as using the int() function. Additionally, the paper discusses other potential causes and alternative approaches, such as NumPy version compatibility issues, but emphasizes type conversion as the best practice. By step-by-step code refactoring and deep type system analysis, this article offers comprehensive technical guidance to help developers avoid such errors and write more robust numerical computation code.
