在Python中,可以使用str.format()方法或f-string(格式化字符串字面量)来格式化数字,包括添加前导零。 示例代码: python # 使用str.format()方法 num = 123 formatted_num_with_format = "{:04d}".format(num) # 指定至少4位数字,不足部分用0填充 print(formatted_num_with_format) # 输出: 0123 # 使用...

1. 使用格式化字符串字面值(f-string)*Python3.6之后 格式化字符串字面值或称 f-string 是带有 'f' 或 'F' 前缀的字符串字面值。这种字符串可包含替换字段,即以 {} 标示的部分。{} 之外的部分按照字面值处理。 可替换字段 {} 可以包含: Python表达式 ...
We don't have to use the str() class to convert the integer to a string as the conversion is done for us automatically. Formatted string literals (f-strings) let us include expressions inside of a string by prefixing the string with f. main.py Copied!my_str = 'is subscribed:' my_...
If base is 0, it 400 is chosen from the leading characters of s, 0 for octal, 0x or 401 0X for hexadecimal. If base is 16, a preceding 0x or 0X is 402 accepted. 403 404 """ 405 return _int(s, base) 406 407 408 # Convert string to long integer 409 def atol(s, base=10)...
你在格式化字符串时最有可能使用的就是f-strings了,因为它们是Python里最新的字符串格式方式。你可以通过使用f-strings展示 today 类: >>> f"{today}" '2023-02-18 18:40:02.160890' 就跟format() 和.format() 一样,f-strings 也展示了 .__str__() 返回的非正式字符串表示。你可以通过在f-string里使...
Use a formatted string literal to add zeros to a float after the decimal. Formatted string literals can use the format specification mini-language to add N zeros to a floating-point number after the decimal. main.py my_float = 3.0 result = f'{my_float:.3f}' print(result) # 👉️ ...
