value = 0.5 # 50% in decimal form percentage = f"{value:.2f}%" # format the value to a string with 2 decimal places and append a "%" sign print(percentage) # output: 50.00% 在Python中,我们可以使用多种方法来输出百分比。最常用的方法是使用print()函数和格式化字符串。从Python 3.6...
name='wtf'print(f'name:{name}')比 format 更简单一些。百分号这种的,纯属清朝老兵。

Use the string format function: >>> from decimal import Decimal >>> d = Decimal("0.0000000000000123123") >>> s = '{0:f}'.format(d) >>> print(s) 0.0000000000000123123 If you just type cast the number to a string it won't work for exponents: >>> str(d) '1.23123E-14' Share...
# 步骤 2: 格式化浮点数到指定的小数位decimal_places=2# 指定需要保留的小数位数formatted_value=f"{float_value:.{decimal_places}f}"# 使用 f-string 格式化 1. 2. 3. 代码解析 decimal_places用于指定您希望保留的小数位数,您可以根据需求调整这个值。
