챕터 1 요약

내장 함수:
- print(), help(), type()
- max(), min(), sum()
- len(), round(), sorted()

모듈:
- string, os

패키지:
- pandas

챕터 2 요약

# Create a custom function
def average(values):
    # Calculate the average
    average_value = sum(values) / len(values)

    # Round the results
    rounded_average = round(average_value, 2)

    # Return rounded_average as an output
    return rounded_average

챕터 2 요약

# Create a custom function
def average(values, rounded=False):

    # Round average to two decimal places if rounded is True
    if rounded == True:
        average_value = sum(values) / len(values)
        rounded_average = round(average_value, 2)
        return rounded_average

    # Otherwise, don't round
    else:
        average_value = sum(values) / len(values)
        return average_value

챕터 2 요약

def average(values):
    """
    Find the mean in a sequence of values and round to two decimal places.

    Args:
        values (list): A list of numeric values.

    Returns:
        rounded_average (float): The mean of values, rounded to two decimal places.
    """

    average_value = sum(values) / len(values)
    rounded_average = round(average_value, 2)
    return rounded_average

챕터 2 요약

# Use arbitrary positional arguments
def average(*args):
    average_value = sum(args) / len(args)
    rounded_average = round(average_value, 2)
    return rounded_average


# Use arbitrary keyword arguments
def average(**kwargs):
    average_value = sum(kwargs.values()) / len(kwargs.values())
    rounded_average = round(average_value, 2)
    return rounded_average

챕터 3 요약

lambda arguments: expression

names = ["john", "sally", "leah"]

# Apply a lambda function inside map()
capitalize = map(lambda x: x.capitalize(), names)

# Convert to a list
print(list(capitalize))

['John', 'Sally', 'Leah']

챕터 3 요약

문자열 'Hello'를 float으로 변환할 수 없음을 나타내는 ValueError 출력

try
except
raise

다음 단계

추가 내장 함수:
- zip()
- input()
- reduce()
- filter()
추가 패키지 및 모듈
- time
- venv
- requests
- fastapi

객체 지향 프로그래밍 입문

대규모 소프트웨어 구축에 필수

축하합니다!
