How can i print out float if the result have decimal or print out integer if the result have no decimal?
c = input("Enter the total cost of purchase: ")
bank = raw_input("Enter the bank of your credit card (DBS, OCBC, etc.): ")
dbs1 = ((c/float(100))*10)
dbs2 = c-dbs1
ocbc1 = ((c/float(100))*15)
ocbc2 = c-ocbc1
if (c > 200):
if (bank == 'DBS'):
print('Please pay $'+str(dbs2))
elif (bank == 'OCBC'):
print('Please pay $'+str(ocbc2))
else:
print('Please pay $'+str(c))
else:
print('Please pay $'+str(c))
exit = raw_input("Enter to exit")

推荐答案
您可以尝试使用简单的Python字符串格式化方法:
You can try this, which simply uses Python's string formatting method:
if int(c) == float(c):
decimals = 0
else:
decimals = 2 # Assumes 2 decimal places for money
print('Please pay: ${0:.{1}f}'.format(c, decimals))
这会给你以下输出如果 c == 1.00
:
This will give you the following output if c == 1.00
:
Please pay: $1
或者如果 c == 20.56
:
Please pay: $20.56
