x=91.234566 print("The value of x upto 3 decimal points is {:.3f}".format(x)) 输出: The value of x upto 3 decimal points is 91.235 我们可以指定传递给方法的变量的位置。在这个例子中,我们使用位置“1”来引用参数列表中的第二个对象,使用位置“0”来指定
Decimal.from_float()− This function converts normal float to Decimal object with exact binary representation. As a result from_float(0.1) and Decimal('0.1') are not same. >>> d1 = Decimal('0.1') >>> d2 = Decimal.from_float(0.1) >>> d1,d2 (Decimal('0.1'), Decimal('0.100000...
Example - decimal points Notice upto 6 decimal points are returned. To specify the number of decimal points, '%(fieldwidth).(precisionwidth)f' is used. print("%f"%5.1234567890) Copy Output: 5.123457 Example - decimal points Notice upto 5 decimal points are returned print("%.5f"%5.1234567890)...

We will first get input values from user usinginput()and convert it to float usingfloat(). We will use the BMI formula, which isweight/(height**2). Then print the result using conditional statements. Here we have usedelifbecause once we satisfy a condition we don't want to check the ...

The part after the "." (3) truncates the decimal part (2346) upto the given number. In this case, 2346 is truncated after 3 places. Remaining numbers (46) is rounded off outputting 235. For keyword arguments Keyword arguments We've used the same example from above to show the differenc...
When we take items in positions 2 to 6, we get four characters with index values 2, 3, 4, and 5. Note that a slice includes the first position and never includes the last specified position, it's an upto but not including rule. Mathematicians call it a half-open interval and write ...
