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(...
python2.7版本中长整型的取值范围为-263-1次方至263次方 python3中没有long类型,使用int表示长整型 #!/usr/bin/env3 python3 >>> 2**63-1 9223372036854775807 >>> L = 9223372036854775807 >>> type(L) <class 'int'> >>> L2 = 9223372036854775808 >>> type(L2) <class 'int'> >>> L3 = -2*...
f-string (Python 3.6+) str.format()方法 字符串旧式格式化(%) 我们将分别使用这些方法来对齐输出。 1. 使用 f-string numbers=[1.1,2.22,3.333,4.4444]fornuminnumbers:# 使用 f-string 格式化输出,宽度为 8,小数点后两位print(f"{num:8.2f}")# {num:8.2f}表示总宽度8个字符,小数点后保留2位 1. ...

Python program to input a number in binary format In this example, we are going to implement the program – that will take input the number as an binary number and printing it in the decimal format. # input number in binary format and# converting it into decimal formattry:num=int(input(...
