假设我们有一组数字,我们希望将它们以左对齐的形式打印出来。我们可以使用format()方法的<选项指定左对齐,并指定输出的宽度。 numbers=[5,10,15,20,25]fornumberinnumbers:print("{:<5}".format(number)) 1. 2. 3. 4. 上述代码的输出结果如下所示: 5 10 15 20 25 1. 2. 3. 4. 5. 在上述代码中...
1. 使用 f-string numbers=[1.1,2.22,3.333,4.4444]fornuminnumbers:# 使用 f-string 格式化输出,宽度为 8,小数点后两位print(f"{num:8.2f}")# {num:8.2f}表示总宽度8个字符,小数点后保留2位 1. 2. 3. 4. 5. 2. 使用str.format() numbers=[1.1,2.22,3.333,4.4444]fornuminnumbers:# 使用 str...

6. 使用第三方模块babel.numbers进行格式化:```python from babel.numbers import format_decimal print(...
Python can evaluate 1+1 just fine, but 1 + 1 is the preferred format because it’s generally easier to read. This rule of thumb applies to all the operators in this section.SubtractionTo subtract two numbers, just put a - operator between them:Python...

format替换「%」说明:This PEP proposes a new system for built-in string formatting operations, intended as a replacement for the existing ‘%’ string formatting operator. No.1 万恶的加号 Python中的字符串在C语言中体现为是一个字符数组,每次创建字符串时候需要在内存中开辟一块连续的空,并且一旦需要修...
print(formatted_number) Similar to f-strings, the format specifier:,adds commas, and.2fensures two decimal places. The output will be the same: 1,234,567.89 Here is the output in the screenshot below. Conclusion In this tutorial, I have explained how toformat numbers with commas and 2 de...
