不間斷 Python 挑戰 Day 2 - 註解、變數與資料型態

註解

# 這是單行註解

'''
這是多行註解
'''

"""
這也是多行註解

print()函數基本功能

# print to console
print("Hello World!")

Hello World!

input()函數基本功能

# input function
input("What's your name?")

What's your name?WJ

變數與資料型態

# string
string_data = "Hello World!"
print(string_data)
print(type(string_data))

Hello World!
<class 'str'>

# integer
integer_data = 123 + 456
print(integer_data)
print(type(integer_data))

# float
float_data = 3.1415926
print(float_data)
print(type(float_data))

# boolean
bool_data = True
print(bool_data)
print(type(bool_data))

579
<class 'int'>
3.1415926
<class 'float'>
True
<class 'bool'>

print("Integer data is " + integer_data)

# type conversion
string_integer_data = str(integer_data)
print("Integer data is " + string_integer_data)

# f-string
print(f"Integer data is {integer_data}")

Integer data is 579
