数值格式化，在数据分析和科学计算等领域，数值格式化是一种常见的需求。通过format()函数可以实现对数值的精度控制、进制转换等操作。例如：num = 100print("The decimal number is: {:d}".format(num))print("The binary number is: {:b}".format(num))print("The hexadecimal number is: {:x}".format(...
print(string) # 输出:text【变量1】text【变量2】text【变量1】text 2 format 字符串格式化方法 2.1 数字:四舍五入/ 百分比/ 千分符 # 当值为整数时和'd'相同,值为浮点数时和'g'相同 # g:保证6位有效数字的前提下用小数表示,否则用科学计数法 ...
首先,我们来回顾一下基本的字符串格式化方法。Python提供了多种方式来格式化字符串,包括%操作符、str.format()方法和f-string(格式化字符串字面量)。 复制 # 使用%操作符 name="Alice"age=30print("My name is %s and I am %d years old."%(name,age))# 使用 str.format()方法print("My name is {}...
第一种: print('%2d-%02d'% (3, 1))print('%.2f'% 3.1415926)# convert an int value to a string and to represent it as a hexadecimal numberprint('%x'% 23004)# refer to variable substitutions by nameprint('Hey %(name)s, there is a 0x%(errno)x error!'% {"name":'jiangwenwen',...
String formatting is essential in Python for creating dynamic and well-structured text by inserting values into strings. This tutorial covers various methods, including f-strings, the .format() method, and the modulo operator (%). Each method has unique features and benefits for different use cas...
