2、内置round() round(number[, ndigits]) 参数: number - 这是一个数字表达式。 ndigits - 表示从小数点到最后四舍五入的位数。默认值为0。 返回值 该方法返回x的小数点舍入为n位数后的值。 round()函数只有一个参数,不指定位数的时候,返回一个整数,而且是最靠近的整数,类似于四舍五入,当指定取舍的小...
str4 = "{name} want to eat {fruit}" str4_new = str4.format(name=dict1['name'], fruit=dict1['fruit']) print('str4 id:{}, content:{}'.format(id(str4), str4)) print('str4_new id:{}, content:{}'.format(id(str4_new), str4_new)) # print("{name} want to eat {fr...

For example, to state the width of number to 4 digits with 2 digits after the decimal point, use the form %4.2f.ExampleTake a look at the following example −#include <stdio.h> int main(){ float num = 5.347; printf("float: %f\n", num); printf("double: %lf\n", num); ...
相对基本格式化输出采用‘%’的方法,format()功能更强大,该函数把字符串当成一个模板,通过传入的参数进行格式化,并且使用大括号‘{}’作为特殊字符代替‘%’使用方法由两种:b.format(a)和format(a,b) format 函数可以接受不限个参数,位置可以不按顺序

Problem As a user: I want to format my number as I do with Python. For example: x = 1000000 print(f"{x:,}") # 1,000,000 Additional context https://discuss.streamlit.io/t/format-integer-with-comma-using-python-printf/2344 Community voting...
Show 4 more comments 32 Only first part of Justin's answer is correct. Using "%.3g" will not work for all cases as .3 is not the precision, but total number of digits. Try it for numbers like 1000.123 and it breaks. So, I would use what Justin is suggesting: >>> ('%.4f' ...
