Format Python datetime as string with strftime

Want to parse a #Python string into a datetime? Use strptime, passing (a) the string and (b) the date format spec: datetime.datetime.strptime('2026-04-01', '%Y-%m-%d') datetime.datetime.strptime('26-April-01', '%y-%B-%d') Both return datetime.datetime(2026, 4, 1, 0, 0)

If a #Python string contains an ISO-formatted date, skip strptime and use datetime.fromisoformat: import datetime as dt dt.datetime.fromisoformat('2026-04-12') # returns datetime at midnight dt.datetime.fromisoformat('2026-04-12 12:34:56') # returns datetime at 12:34:56

🔢 Python Program: Prime Number ```python num = 7 if num > 1: for i in range(2, num): if num % i == 0: print("Not Prime") break else: print("Prime") ``` 💡 Builds logic thinking #Python #Logic

📊 Python Program: Frequency Counter ```python numbers = [1, 2, 2, 3, 3, 3] freq = {} for num in numbers: freq[num] = freq.get(num, 0) + 1 print(freq) ``` 💡 Use case: ✔ Log frequency analysis #Python

Want to round #Python #Pandas datetimes? You have 3 options: - dt.floor — earlier - dt.ceil - later - dt.round — nearest For example: s.dt.floor('3h') # previous multiple-of-3 hour s.dt.ceil('15m') # next 15-minute block s.dt.round('1D') # nearest 1 day

🔁 Python Program: Fibonacci Series ```python n = 6 a, b = 0, 1 for _ in range(n): print(a) a, b = b, a + b ``` 💡 Builds strong logic thinking #Python #Logic

Want to check if two #Python #Pandas datetimes are in the same month/quarter/year? Convert them both to periods, and compare with ==: date1.to_period('M') == date2.to_period('M') # same month? date1.to_period('Q') == date2.to_period('Q') # same quarter?

In Python, mutable default arguments can behave unexpectedly. def add_item(item, my_list=[]): my_list.append(item) return my_list print(add_item(1)) print(add_item(2)) Output: [1] [1, 2] Why? Because the default list is created only once and reused. 𝗙𝗶𝘅: def add_item(item, my_list=None): if my_list is None: my_list = [] my_list.append(item) return my_list 𝗞𝗲𝘆 𝗜𝗻𝘀𝗶𝗴𝗵𝘁: Default mutable objects persist across function calls. That’s why unexpected bugs happen. #Python #PythonTips #Programming #Developers #Coding #Tech #LearningPython

🔄 Input & Output in Python input() → take user input print() → show output Use case: Take server name → display status Simple but powerful. #PythonBasics

🚀 Truthiness and Falsiness in Conditional Statements (Python) In Python, values other than True and False can also be evaluated in conditional statements. Values like empty strings, zero, empty lists, and None are considered 'falsy', meaning they evaluate to False in a boolean context. Non-empty strings, non-zero numbers, and non-empty lists are considered 'truthy', evaluating to True. This allows for concise conditional checks based on the presence or absence of data. #Python #PythonDev #DataScience #WebDev #professional #career #development
