🏆 BONUS –How to round each item in a list of floats to 2 decimal places in Python? Before wrapping up this discussion, let us have a quick look at a couple of methods that allow you to round each float value within a list to 2 decimal places. Problem: Given the following list,...
print("{0:+^20}".format("Python"))#输出:+++++Python+++++ #还可以不需要槽样式,直接将槽样式写在format函数的参数里 print(format("Hello"),format("World")) #输出:Hello World! print(format("Python",'+<20'))#输出:Python+++++++++ print(format("Python",'+>20'))#输出:+++++++++...
# set precision to 2 for floating-point numberprecision_value = format(123.4567,'.2f') print(precision_value)# Output: 123.46 Run Code Here,.2fmeans two digits will be shown after the decimal point. Also Read: Python String Interpolation...
/><br />如果没有给出精度,则使用精度为6 [float] 的有效数字。 对于Decimal”,结果的系数由值的系数位数构成; 科学记数法用于绝对值小于“1e-6”的值和最低有效位的位值大于1的值,否则使用定点记数法。< /><br />无论精度如何,正负无穷大,正负零和nans 分别被格式化为inf、-inf、0、-0和nan`...

To format floating-point numbers, use the code “f”. To determine the precision or number of decimal places, use’.’ followed by a number. Specify the width and alignment using <, >, or ^. Code: num = 4.14159 print("Kindly Print a Float Number: {:.2f}".format(num)) ...
使用加号(+)操作符和转换函数(如IntToStr),你确实能把已有值组合成字符串,不过另有一种方法能格式化数字、货币值和其他字符串,这就是功能强大的Format 函数及其一族。 Format 函数参数包括:一个基本文本字符串、一些占位符(通常由%符号标出)和一个数值数组,数组中每个值对应一个占位符。例如,把两个数字格式化为...
str3 = "{1} want to eat {0}" str3_new = str3.format('渔道', '苹果') print('str3 id:{}, content:{}'.format(id(str3), str3)) print('str3_new id:{}, content:{}'.format(id(str3_new), str3_new)) dict1 = {'name':'渔道', 'fruit':'苹果'} ...
