match command:
case 1:
print(“Menu 1”)

python forの中でforを使ってみる

initial_balance = int(input(“Initial Balance? “))
RATE = 1.1

for i in range(3):
if i != 0:
initial_balance += 10_000
for year in range(3):
print(f”Year {year}: {initial_balance * RATE ** year:,.2f}”)

Python forとf文字を組み合わせる

initial_balance = int(input(“Initial Balance? “))
RATE = 1.1

print(f”Year 0: {initial_balance:,.2f}”)

print(f”Year 1: {initial_balance * RATE:,.2f}”)

print(f”Year 2: {initial_balance * RATE * RATE:,.2f}”)

print(f”Year 0: {initial_balance * RATE ** 0:,.2f}”)

print(f”Year 1: {initial_balance * RATE ** 1:,.2f}”)

print(f”Year 2: {initial_balance * RATE ** 2:,.2f}”)

for i in range(3):

print(f”Year {i}: {initial_balance * RATE ** i:,.2f}”)

for year in range(10):
print(f”Year {year}: {initial_balance * RATE ** year:,.2f}”)

python for

#for i in range(10):

for i in range(8, 5, -1):
print(f”{i} Hello!”)

python matchとif

initial_balance = int(input(“Initial Balance? “))

match initial_balance:
case n if n >= 100_000:
RATE = 1.1
case n if n >= 80_000:
RATE = 1.08
case n if n >= 60_000:
RATE = 1.06
case _:
RATE = 1.01
print(f”Current rate: {RATE:.2f}”)
print(f”Year 0: {initial_balance:,.2f}”)
print(f”Year 1: {initial_balance * RATE:,.2f}”)
print(f”Year 2: {initial_balance * RATE * RATE:,.2f}”)

Python ifelse

initial_balance = int(input(“Initial Balance? “))

RATE = 1.1 if initial_balance >= 100_000 else 1.01
print(f”Current rate: {RATE:.2f}”)
print(f”Year 0: {initial_balance:,.2f}”)
print(f”Year 1: {initial_balance * RATE:,.2f}”)
print(f”Year 2: {initial_balance * RATE * RATE:,.2f}”)

Python matchで条件分岐

match signal:
case “red”:
print(“Stop”)
case “yellow”:
print(“Slow down!”)
case “blue” | “green”:
print(“Go!”)
case _:
print(“Invalid signal color…”)
