Przygotowanie

Upewnij się, że masz zainstalowany interpreter Python 3. Jeżeli nie, skonsultuj się z prowadzacym
W katalogu domowym przygotuj katalog AD, a w nim mod1
Twórz po kolei pliki skryptów z rozszerzeniem py dla każdego zadania z tego warsztatu wg. wzorca: app-1-1.py, app-1-2.py itp.
Wywołuj skrypty w terminalu

print("My name is "+name.upper())
print("   "+str(type(name)))
print("My age is "+str(age))
print("   "+str(type(age)))
print("I'am a male "+str(isMale))
print("   "+str(type(isMale)))
print("\nI like "+like+" as much as "+str(len(like))+" between 0-10")
print("I hate "+hate+" with length of ")
print(len(hate))

1.6Ciągi tekstowe jako tablice

# Time:	6 minutes
# Go!
name = "Grzegorz"	# String
age = 30			# Number
isMale = True		# Boolean
like = "Lemonade"	# String
hate = "Garlic"		# String

print("My name is "+str(name.index("z")))
print("My age is "+str(age))
print("I'am a "+str(isMale)+" male")
print("\nI like "+like[0].lower()+like.replace(like[0],""))
print("I hate "+hate[0])

1.7 Wartości liczbowe

now = "2020"		# String
age = 1987			# Number
weight = 96.5		# Number (decimal)
isMale = True		# Boolean
like = "Microsoft"	# String
strength = -10		# Number (negative)
hate = like			# String

print("My name is "+name)
print("My weight is "+str(weight)+" at age "+str(int(now)-age))
print("Simple weight: "+str(round(weight)))
# lib IMPORT needed
print("True weight: "+str(ceil(weight)))
print("Fake weight: "+str(floor(weight)))
print("\nI like "+(like[0].lower()+like.replace(like[0],""))+" with strengt of "+str(strength))
print("I hate "+hate+" with strengt of "+str(abs(strength)))
