Control Statements

Follow along: Control Statements

The program launching process along with parameter settings are all simplified and set up on the Jupyter Notebook Environment.

• Create a new *.ipynb file Jupyter Notebook
• Fill in the content below in the newly created file
• Follow and Execute the example codes

(The Jetson Board used for these examples are => Jetson Nano)

• Let’s write the following examples.

if Statement

# 1
money = 0

if money:
    print('money :', money, ', ",Take a taxi"')

else:
    print('money :', money, ', ",Go on foot"')

# 2
money = 500
card = 1

if (money >= 30000 or card == True):
    print('"Take a taxi"')

else:
    print('"Go on foot"')

# 3
pocket = [500, 'cellphone']
money = pocket[0]
print('pocket: ', pocket)

if (money >= 30000 or 'card' in pocket):
    print('"Take a taxi"')

elif 'cellphone' in pocket:
    print('"Call mom"')

else:
    print('"Go on foot"')

while Statement

# 1

while (a < 10):
    print('a :', a)
    a += 1

# 2

while (1):
    print('b :', b)
    b += 1
    if (b == 10):
        break

print("I succeeded in running away!")

# 3

while True:
    print('c :', c)
    c += 1

    if (c != 10):
        continue
    print('Can you see my writing?')

    if (c == 10):
        break

    print('Press "ctrl+c" to exit')
