Python：TypeError 需要 integer（获取类型 str）

Question

print(Datedetail) -> 2020-10-31 00:00:00
print(type(Datedetail) -> <class 'datetime.datetime'>
print (DateDetail.replace('-',''))[:6]) -> TypeError: an integer is required (got type str)

Datedetail is having value of date and time but while replace special char and having only date details it is giving error as integer is required.

Answer 1

You cannot use the str.replace() method on a datetime.datetime class.

Use str to convert it into a string:

print(str(Datedetail).replace('-','')[:6])

Output:

202010

---

Recommendation: usestrftime instead of datetime .

Answer 2

Make use of.strftime() to get dates into format you want.

Datedetail.strftime('%Y%m')

Answer 3

The replace function is not the same as you use for strings. https://docs.python.org/2/library/datetime.html#datetime.date.replace

You have to make it to a string first, so it has its usual behaviour: print(str(Datedetail).replace('-','')[:6])

But usually you would use string formatting as you can find as well in the documentation above: date.strftime(format)
