既然你已经学会了如何创建和运行Python 脚本,那么以前需要手动实现的业务过程,现在完全可以通过编写Python 脚本来自动化和规模化地完成。后面几章会详细介绍如何使用Python 脚本来自动化和规模化地完成任务,但是在进行下一部分内容之前,还需要掌握更多的Python 语言基础要素。通过掌握更多的基础要素,你会对Pytho
Yes, there is a difference. The join() method will require you to explicitly convert the numbers to strings before joining, whereas the str() function will convert the entire list to a string with brackets and commas, including the non-string elements. If you want a specific format for the...
replace(" ", ",") print("Output #33 (with commas): {0:s}".format(string5_replace)) # 字符串转小写、转大写、首字母大写 string6 = "Here's WHAT Happens WHEN You Use lower." print("Output #34: {0:s}".format(string6.lower())) string7 = "Here's what Happens when You Use ...
