Traceback (most recent call last):

print(datetime.datetime.strptime("test_str", "%m/%d/%Y").strftime("%Y-%m-%d") )
raise ValueError("time data %r does not match format %r" %
I tried to read the user entered date as the input and display it in the format as i desire
import datetime
test_str=input("Enter date")
format= "%m/%d/%Y"
try :
res= bool(datetime.strptime(test_str,format))
except:
print("The Date is not in the required format" )
print(datetime.datetime.strptime("test_str", "%m/%d/%Y").strftime("%Y-%m-%d") )
我期待它以所需的格式給出日期
uj5u.com熱心網友回復：
您必須以相同的格式“%m/%d/%Y”進行輸入，否則將無法正常作業。
試試看：
import datetime
test_str=input("Enter date")
format= "%m/%d/%Y"
try :
res= bool(datetime.strptime(test_str,format))
print(datetime.datetime.strptime("test_str", "%m/%d/%Y").strftime("%Y-%m-%d") )
except:
print("The Date is not in the required format" )
