Python程序将十进制数转换为二进制数
给定一个十进制数作为输入,任务是编写一个Python程序将给定的十进制数转换为等效的二进制数。
例子 :
Input : 7
Output :111
Input :10
Output :1010
方法#1:递归解决方案
DecimalToBinary(num):
if num >= 1:
DecimalToBinary(num // 2)
print num % 2
下面是上述递归解决方案的实现:
Python3
# Function to convert decimal number
# to binary using recursion
def DecimalToBinary(num):
if num >= 1:
DecimalToBinary(num // 2)
print(num % 2, end = '')
# Driver Code
if __name__ == '__main__':
# decimal value
dec_val = 24
# Calling function
DecimalToBinary(dec_val)
Python3
# Python program to convert decimal to binary
# Function to convert Decimal number
# to Binary number
def decimalToBinary(n):
return bin(n).replace("0b", "")
# Driver code
if __name__ == '__main__':
print(decimalToBinary(8))
print(decimalToBinary(18))
print(decimalToBinary(7))
Python3
# Python program to convert decimal to binary
# Function to convert Decimal number
# to Binary number
def decimalToBinary(n):
return "{0:b}".format(int(n))
# Driver code
if __name__ == '__main__':
print(decimalToBinary(8))
print(decimalToBinary(18))
print(decimalToBinary(7))
输出
011000
方法#2:使用内置函数将十进制转换为二进制
Python3
# Python program to convert decimal to binary
# Function to convert Decimal number
# to Binary number
def decimalToBinary(n):
return bin(n).replace("0b", "")
# Driver code
if __name__ == '__main__':
print(decimalToBinary(8))
print(decimalToBinary(18))
print(decimalToBinary(7))
输出
1000
10010
111
方法#3:没有内置函数
Python3
# Python program to convert decimal to binary
# Function to convert Decimal number
# to Binary number
def decimalToBinary(n):
return "{0:b}".format(int(n))
# Driver code
if __name__ == '__main__':
print(decimalToBinary(8))
print(decimalToBinary(18))
print(decimalToBinary(7))
输出
1000
10010
111
