[英]Are indented code under an `if` and a `def` both called blocks in Python?
[英]My code works when not indented and not in a def function in python
當我的代碼不在 def 函數中並且沒有縮進時,我有一段代碼可以正確運行。 這是我縮進時的代碼。
import csv
my_file = open("marqueeTables.csv", "r")
search_data = input("Please enter the data you are looking for")
search_data = (search_data + " metre wide")
#print(search_data)
reader = csv.reader(my_file)
for row in my_file:
if search_data in str(row): # == "6 metre wide":
stripedRow = row.strip()
splitStrippedRow = stripedRow.split(",")[0]
print(splitStrippedRow)
#print(row)
It prints "6 metre wide" or "12 metre wide" depending on whether I type 6 or 12.
這是類似的代碼,但在 def 中(僅更改了一些內容):
def userInfo():
while True:
w = str(input("What size width marque would you like 6 or 12: "))
if w == "6":
myFile = open("userDetails.csv", "a+")
myFile.write(str(w) + ", ")
myFile.close()
break
elif w == "12":
myFile = open("userDetails.csv", "a+")
myFile.write(str(w) + ", ")
myFile.close()
break
else:
print("Pleas type 6 or 12")
w = (w + "metre wide")
my_file = open("marqueeTables.csv", "r")
#search_data = input("Please enter the data you are looking for")
reader = csv.reader(my_file)
for row in my_file:
if w in str(row):
stripedRow = row.strip()
splitStrippedRow = stripedRow.split(",")[0]
print(splitStrippedRow)
userInfo()
當我運行代碼時,它再次打印“6 米寬”和“座位容量”和“12 米寬”和“座位容量”(因為它在表格中出現了兩次。)
有人能告訴我為什么我的代碼不能在 python 中工作,謝謝,那就太好了。 我正在使用 python 3.5。 謝謝
在第二個代碼示例中,您定義了userInfo
,但從不調用它,因此它從不運行。
