示例：name = 'Alice'age = 25formatted_string = "My name is {} and I am {} years old.".format(name, age)print(formatted_string)输出结果：My name is Alice and I am 25 years old.2. 使用位置参数：可以通过位置参数指定要替换的值的顺序。示例：name = 'Bob'age = 30formatted_string = ...
Perform a string formatting operation. The string on which this method is called can contain literal text or replacement fields delimited by braces {}. Each replacement field contains either the numeric index of a positional argument, or the name of a keyword argument. Returns a copy of the st...

Conversion types f and F convert to a string representation of a floating-point number, while e and E produce a string representing E (scientific) notation:Python >>> "%f, %F" % (3.14159, 3.14) '3.141590, 3.140000' >>> "%e, %E" % (1000.0, 1000.0) '1.000000e+03, 1.000000E+03' ...
print(f"scientific: {number:e}") print(f"Number: {number:09}") print(f"千分位表示法: {number:,}") 或者,如果您希望f字符串输出百分比值,可以使用:.2%,这会告诉Python将值设置为小数点后两位,并在字符串末尾添加百分号。 percentage = 0.1234 ...
使用scientific notation表示数字 科学技术法是一种用于表示很大或者很小的数字的方法,通常以数字乘以10的幂的形式来表示。例如,1.23 x 10^6表示为1.23e6。 在Python中,科学技术法表示的数字可以直接赋值给变量,例如: num=1.23e6print(num) 1. 2. 将科学技术法转换为字符串 ...
