習題7 - 更多打印

用Notepad++打下列的程式碼,
另存為ex7.py.

print ("Mary had a little lamb.")
print ("Its fleece was white as {}.".format("snow"))
print ("And everywhere that Mary went.")
print ("." * 10) # what'd that do?

end1 = "C"
end2 = "h"
end3 = "e"
end4 = "e"
end5 = "s"
end6 = "e"
end7 = "B"
end8 = "u"
end9 = "r"
end10 = "g"
end11 = "e"
end12 = "r"

# watch that comma at the end. try removing it to see what happens
print (end1 + end2 + end3 + end4 + end5 + end6, end = " ")
print (end7 + end8 + end9 + end10 + end11 + end12)

然後用Windows的cmd, 執行python打開它.

C:\Windows\System32>cd C:\Users\Peter\Desktop\Python\LP3THW

C:\Users\Peter\Desktop\Python\LP3THW>python .\ex7.py
Mary had a little lamb.
Its fleece was white as snow.
And everywhere that Mary went.

完成

這次練習主要是學習把一個字串放進另外一個字串.
Line 3 - 4, 我用另外一種方式表達出來跟上面相同的結果.
Line 6, 主要是學習將字符"@"連續乘10次
Line 22, 主要是學習接著打印在同一行.我將之修改為"_"

print ("Mary had a little lamb.")
print ("Its fleece was white as {}.".format("snow"))
SNOW = "snow"
print (f"Its fleece was white as {SNOW}.")
print ("And everywhere that Mary went.")
print ("@" * 10) # what'd that do?

end1 = "C"
end2 = "h"
end3 = "e"
end4 = "e"
end5 = "s"
end6 = "e"
end7 = "B"
end8 = "u"
end9 = "r"
end10 = "g"
end11 = "e"
end12 = "r"

# watch that comma at the end. try removing it to see what happens
print (end1 + end2 + end3 + end4 + end5 + end6, end = '_')
print (end7 + end8 + end9 + end10 + end11 + end12)

結果,

C:\Users\Peter\Desktop\Python\LP3THW>python .\ex7.py
Mary had a little lamb.
Its fleece was white as snow.
Its fleece was white as snow.
And everywhere that Mary went.

Line 3 & 4, 是相同的結果. 這是我用另外一種方式表達.
